CTHON Update - 4/12/2022
Hello everyone! After far too long, CTHON has finally been updated to the Game Maker Studio 2 engine from Game Maker 8.1! This has been all about making sure the source code doesn't sit there and rot and that the game continues to be stable on newer OSs. A few minor bugs have bee

A New Company, and a New Game in the Works
Hello everyone! It has been a couple years since there was a concrete update on what is happening with Gravity Games, and CTHON. Here is what is happening: When I released CTHON, it was under the name of a sole proprietorship, called Gravity Games. In the following years, I partn

Hi everyone, Just a quick patch to fix a bug:
Bug Fixes

Fixed a bug where an error would be thrown on the final score screen (after defeating the final boss) if the game was saved and exited right before the final boss level.
Note: If you notice the file sizes are hundreds of megabytes, don't be alarmed; because of the way Game Maker works, I have to overwrite the executable entirely whenever I recompile the game with code changes. Download sizes for CTHON at the moment should be right around 244 MB, though that number will slowly rise as additional code is added.

Bug Fixes

Fixed another (and hopefully the last) potential crash bug that is related to audio playback issues on (from what I know so far) Window 8 and 8.1 sound drivers.
Fixed a bug where one of the attacks used by the final boss would miscalculate its damage.
Stay tuned for more updates soon!

Hey all! Here is what is new to CTHON:
Balance Changes

Revamped item spawning to be more forgiving, especially on later levels. Resource items (health, ammo, and grenades) reduce less rapidly per level. This is most noticeable in the late game. Each difficulty is different in how rapidly it reduces item count per level; Beginner has a flatter curve, while Hardcore has a steeper curve. Item spawning is still random, but generally not as scarce.
Revamped the way secrets spawn so that they have less of an overall impact on the game; some secrets can still contain very good loot, not so good loot, and even monsters, but there are now far less secrets on any given level and they more frequently spawn in larger blank areas instead of on obscure corners.
The player now starts with two inventory slots instead of just one.

Bug Fixes

Fixed a bug where the score screen would start to incorrectly report the number of total secrets found if you started a new run without closing the application.

Other Changes

Changed the game's font to something more legible and less wide.
Added seams to the textures of secret walls to make them easier to find.
Thanks and have fun!

Hi everyone! This update has come early due to a crash bug that needed fixing. Here is what is new in CTHON:
New Features

Added a new item (this was originally planned for the May update) - Large Nanite Unit. This item provides 25 nanites. This is a subtle change, but it should allow you to be a little more liberal with spending nanites.

Bug Fixes

Fixed a crash bug related to audio playback issues on Windows 8 and Windows 8.1, caused by Wyrm enemies.

Known Issues

Alt Tabbing causes the Strafe On control (when mapped to Alt, which is the default) to stick. A workaround is to tap Alt again when you refocus on the game window.
Thank you, and enjoy!

Hi everyone! Here is what is new in CTHON:
New Features

The game can now run in a window. Use F4 at any time to toggle between windowed and fullscreen modes. You can also Alt-Tab out as well as resize the window by dragging the edges.
The game now has one resolution mode for launch (an emulated 640x480 display); the forced 640x480 mode was causing more problems than it was worth. Higher resolutions are planned for a later patch. This may cause display issues with certain recording software, so if you plan to record gameplay you may need to configure your software for window capture.
Added a "Strafe On" key that defaults to Alt. Holding this key allows you to use Turn Left and Turn Right to strafe in the corresponding direction. Ideal for old-school keyboard setups.
Added back in a brief overview of the controls. A message at the beginning of the game displays to inform players to use F1 for a list of controls.
Added extra sounds for weapons equipped with several damage upgrades.
Added a new type of map piece.
Changed the way health, ammo, and bombs display - they are now displayed in an x/x form.

Bug Fixes

Fixed a bug where mapping a control to one of the mouse buttons would cause every key to perform that action.
Fixed a bug where saving and exiting would not record the total time of the run accurately.

Balancing

Rebalanced the way items spawn. In particular, the previous version was spawning too many Framework Nodes to be practical.
Removed items in the final boss fight. The reason for this was to increase the level of tension at the end of the game and require some planning on the player’s part.
The Blade now deals higher base damage for all classes (and the Berserker still starts with more than the other classes). This will hopefully make melee a little more viable.
Berserker now starts with slightly faster base speed.
Sapper now starts with slightly faster launcher fire rate.
Thank you, and enjoy! EDIT: The next major update will be planned for between May 5 and May 12, 2017. Please don't hesitate to report bugs in the Bug Reports section of the forum, and request new features in the Feature Requests section! Generally, large features must be planned for the following patch, but small things that are relatively easy to implement can usually be bumped up the list, and of course, major bugs always take high priority. I will also be looking at implementing Achievements for this month. Thanks again!
