v1.1.11 Patch Notes
This update includes a fix for some memory leak issues. Other than that, this update mainly just involves internal engine changes. This should translate to a smoother and more stable experience for players.

Back again with another small patch.

Fixed an issue with copied save files not remembering what items have been collected.
Fixed an issue where changing Shin's costume while in-game did not consider if demonblade was unlocked.
Improved controller glyphs and button prompts for Steam Deck and Xbox controllers.
Most settings (audio, video, bindings, etc.) will now prefer local settings instead of Steam cloud sync. Players who use multiple devices often have different resolutions or controller setups depending on device, so it is more convenient if the game does not try to revert these every time they switch from one device to another.
The video menu will now display the resolution of the current display when fullscreen is enabled.

v1.1.7 - Fixed Projectiles
This is a quick patch for an issue that was introduced in the previous update. While trying to fix an issue with Mother's projectiles becoming invulnerable, a new bug was created which caused some projectiles to change speed or behave strangely. This update resolves that issue. H

This update has minimal impact to the core game, but there are a few bug fixes included. The focus instead is around the Twitch Arena, and providing a more customizable experience for the host.
Arena updates
Here are the updates related to the Twitch arena in this patch:

Added option in Twitch Arena for a One Hit battle. This can be toggled on and off before starting the fight with a statue in the arena room. Enabling this allows you to fight as if the game difficulty was set to "One Hit", regardless of what difficulty your save file is. - You must complete the game at least once to unlock the One Hit difficulty before this option is available.
Dying in the arena will now respawn the player in the same room. No more do you need to run all the way back to the arena. :D
Individual spawn limits for each supported boss is now configurable in the twitch_config.ini file.
Disconnecting from the arena (either from timeout or with the !disconnect) command will now respawn the target so you can start a new fight without leaving the room.
Added an optional voting system. This allows you to space out the spawn rate between bosses in the arena. Any time a user enters a command, it instead places a "vote" for that boss, and when the time expires it spawns one boss from the list randomly. Voting on the same boss increases the odds, but every vote has the potential to be picked! - This can be enabled by setting "votingDelay" greater than 0 in the twitch_config.ini. - The voting system does not apply to non-boss commands like !rock.
Since there were config changes in this patch, your twitch_config.ini may be overwritten by the update. You will need to obtain a new oauth token and update the config next time you plan to use the Twitch Arena. The "Twitch Arena Guide.txt" file has also been updated to reflect the new options in the config.
Other changes
In addition, there are a few changes worth mentioning that apply outside of just the Twitch Arena. Here is the breakdown of what to expect in 1.1.6:

Fixed an issue which incorrectly prevented projectiles from being hit when they spawned under certain conditions.
Fixed an issue with respawning during boss rush sometimes placing the player in the wrong room.
Health bars no longer display in One Hit difficulty, as they aren't relevant.

v1.1.5 - Menu improvements and polish

This update includes several bug fixes and quality-of-life improvements.

Fixed Steam achievements and cloud saves not working on Mac.
Added binding option for menu confirm and back. These are now separate from attack, jump, and roll.
Changed file delete and "Restore to Defaults" buttons so they now display a confirmation window instead of needing to be held down.
Fixed "Restore to defaults" resetting some unlock progress.
Improved consistency for exiting in-game menus, like the map and scroll display. Escape now exits universally, in addition to the menu back button.
Fixed an issue with the parry move consuming too much magic depending on the order in which buttons were pressed. It now consistently uses 1 magic bar.
Added magic consumption indicator on the scroll for acquiring the parry move.
Improved compatibility, localization, and visual prompts for certain controllers, such as Switch Joy-Cons and DualShock 4.
Fixed dodge ability ending invulnerability prematurely.
Fixed an issue with twitch_config.ini not working unless it is in the same folder as the exe on Windows. (It should now work from the twitch_arena folder as intended.)
Fixed an issue that could allow binding D-pad buttons to actions which are invalid. (D-pad is always used for movement.)
Fixed an issue that prevented looking at the EWLS scroll with cutscene skipping on.
Fixed a visual issue where a frozen Bandit could be shown if approached from an unintended method.

Ato version 1.0.9 is out now. This update includes the following changes:

Fixed a bug with warp gates.
Grass has a long memory... It remembers when it has been cut.
For all those speedrunners out there, v1.0.8 will continue to be available in case you want to utilize the warp glitch. (It is recommended to update unless you plan on running the "All Glitches" category.) To download 1.0.8, open the game properties and go to the Betas tab. Select "speedrun_1.0.8" branch.
Please note: Loading a save file in an older version after it was opened in a newer version can cause loss of data. Use caution when switching between versions and only open new save files when running an older version.

v1.0.8 Mac and Linux Release

Ato is now available on Linux* and MacOS! Both M1 and Intel CPUs are compatible on MacOS.
It's the same game you know and love now more accessible than ever. This additional platform support means that it should be fairly optimized to run on Steam Deck as well, once it releases. We plan to apply for a Steam Deck verified rating (and test it on the hardware ourselves) as soon as possible, but it might be several months after Steam Deck releases due to Ato's relative obscurity in Steam's wide library of games.
As a reminder, the Steam autumn sale is still going on. If you've been waiting for a Mac release to pick up Ato, now is a great time to get it while it's still on sale! ːJumpyCuteː
*The game's engine (GameMaker Studio 2) only officially supports Ubuntu 18.04 and 20.04. (Steam itself only supports Ubuntu and SteamOS). That said, it should generally work on most Linux distributions, but may require additional steps and workarounds. As such, Ato only officially supports Ubuntu and SteamOS as well.
Miscellaneous Updates
Since the last update, a few more minor fixes have made their way in, hence the update to version 1.0.8.

Turtle no longer gets stuck in the left side wall when rolling.
Minor updates to some in-game menu translations.
Fixed stretching on resolutions that do not have a 16:9 aspect ratio.
Fixed a potential crash on Champ, Guardian, and Twins. (This bug was discovered with the Mac build where it happened consistently; it's unknown if this crash was possible on Windows before. In any case, it's fixed now.)

The last update introduced an issue with the window size for displays that don't have an ideal resolution. This patch fixes that. (Thanks to Octopoos from the Discord for reporting this bug and helping test the fix.)
The demo has been updated to the latest version. The last time the demo was updated was 1.0.6.4, so this means the demo now gets all the bug fixes and optimizes that have happened since then.
Credits have been updated to include individuals who helped with the previous localization update.

Ato is now more accessible than ever! Although the gameplay does not rely on any text, navigating menus is a lot easier if they are in a language you speak! This update adds multiple new language options including Arabic, Dutch, Danish, Polish, Swedish, Finnish, and more.
In addition, the store page and achievements have all been localized to these languages, as well as most of the other languages which previously only had localized menu text. The remaining ones (Japanese, German, and Korean) will be fully localized in the near future.
Some languages have also had their translations updated to be more accurate and natural than they were before. If you notice any issues, please let us know either through the Steam discussions or in our Discord.
New players will be prompted to select a language the first time they launch the game, but you can always change your preferred language from the settings menu.
There's more...
While the focus of this update is clearly on translations, there are a few other improvements alongside this patch.

Controller vibration has been added. You can disable this from the Gameplay settings if you prefer. Vibration only occurs if you are actively using a controller, so mouse and keyboard users do not need to turn this off.
Fixed an issue with a certain achievement not triggering if auto-skip cutscenes is turned on.
Fixed an issue with stretching that sometimes occurred when switching between fullscreen and windowed.

This patch fixes a critical issues with the tiles not displaying for one region of the game. It also includes a fun minor changes to polish up rough edges:

Scrolls for abilities that use magic now display how many magic bars the ability requires. This is especially useful for Fatal Draw, as it's possible to obtain without having enough magic to use it right away.
Some puzzles will now be automatically completed if you have already obtained the orb from that path. This reduces the pain of backtracking if you have to return to these areas because you missed a pickup or side-room the first time.
Reduced noise from a few more sound effects when they overlap, for a softer auditory experience.
Fixed an issue with enemies being able to trigger the combo achievement.
Our last patch was a bit too loose with the grass dye; we've corrected the color of the grass on a specific encounter.

Fixed a memory leak which could cause crashes for some users after extended play sessions.
Optimizations to reduce reliance on shaders. This can provide a fairly significant performance boost on devices which have integrated graphics or a weaker GPU.
Fixed an issue with grass spawning inconsistently. (That is to say, it often didn't spawn!)

Since the last update, Ato has been updated to version 1.06.1 and now 1.06.2. These updates mainly just fix a few bugs in the 1.06 release, namely:

Fixed issue with Boss Rush respawning you in the incorrect room under certain circumstances.
Fixed issue that sometimes caused bosses to get stuck after spawning. (This was most prevalent with Leader and Twitch arena.)
Fixed a crash when holding dash after a certain boss battle.
Improved controller support/detection. You should now be able to switch between controllers seamlessly and no longer need to use the gamepad in slot 1.
Fixed PlayStation controller button prompts displaying incorrectly.
Added visual hints for a certain boss's spawn condition. Hopefully players will be less confused by this now when arriving at an empty room.
In addition to these changes, the demo has been updated. It contains the same amount of gameplay as the old demo, but is based on the latest build of the game. This has a number of benefits including tons of bug fixes, settings in the menu, and your save file will transfer over to the full version.

A new update has just dropped and along with it comes an exciting new mode: Boss Rush! This mode allows you to experience raw action as you fight through the bosses* back-to-back.
Unlock condition: Achieve 100% completion and beat the game on any save file.
In this mode, all of your abilities will be available from the start. You can choose any difficulty. You will start with max health, but you'll have to be careful because your health does not restore between fights! Challenge yourself to clear them all as quickly and with as few deaths as possible.
*All bosses and arenas are included in this mode, with the exception of the following:

3 joke fights against Vagrant. (The final fight against him is included.)
Child - This is more of a platforming challenge than an actual "fight." It didn't fit in with the frantic combat focus of Boss Rush, so it was left out.
Optimizations, Bug Fixes, etc.
In addition to the new mode, this update includes a ton of bug fixes and optimizations. This should result in a smoother performance, especially for players with weaker PCs.
New graphics settings have been added in the menu to reduce graphical effects and improve performance even further. It's recommended to play on full settings if your computer can handle it, but if it is struggling feel free to turn down the particles, water quality, and/or lighting as needed.
Also, an issue that prevented the grass setting from working correctly when auto-optimize was turned off has been fixed.
Enjoy!

Fixes for a variety of bugs and adds a little extra polish. Here are a few of the included changes:

Fixed a lot of sound effects not respecting the audio settings. Also reduced instances of overlapping sound effects to eliminate those ear-popping audio spikes!
Fixed one spot where the player could get stuck while backtracking if they did not have certain abilities.
Fixed inconsistent layering of certain objects in specific rooms.
Chinese, Korean, and Japanese fonts now use their own font file. This makes loading them marginally faster in the language selection screen and takes less memory.
Added a way for players to escape when trapped inside a wall of breakable blocks.
In addition, this update brings some improvements for the Twitch arena! This feature is mainly intended for streamers, but don't worry - it is 100% optional and does not impact game completion or unlocks.
Familiar with Twitch but don't know how to use the arena? Check the game files - there's a guide there telling you how to set it up! ːHoppyStandː Here are the new enhancements:

Arena now has an icon on the map so you can find it again easily.
Added a setting to the config for limiting the overall number of simultaneous bosses - useful for a bigger audience to prevent things from getting out of hand.
Fixed an issue where boss limits were based on total number that had been spawned, rather than the number currently alive.
While the arena is active it will now display the number of bosses defeated and a timer for time alive.
Added an additional command to the bot's command list message that was previously left out.
10 more bosses added as commands! These bosses require that you defeat them on the same save file in order for them to be available in the arena. They are:

Acolyte
Geisha
Berserker
Sentinel
Samurai
Cross Blade
Champ
Daggerman
Tempest
Bandit

What's next?
The next update will be focused on optimization and providing more graphics options, particularly to help users with weaker PCs get better performance. There's more to come, folks! Hope you are enjoying Ato!
