Hello my Kritters!
I know it's been a while and I'm sorry for that but we had to take a break after the release and debugging month that followed.
But during our absence, we did take some rest and, we worked hard on the next updates for Kritter.
The 1.0.15 update will just bring more bug fixes, optimization and first attempt of anti cheat to avoid poluting the leaderbaords.
Feel free to check the patch note below.
What about the 1.1?
Of course we didn't spend all that time just on those nasty bugs.
We've been working on the 1.1 and its biggest feature, the local co-op.

It has been a huge challenge as we had to entirely redo all of the UIs in the game and adapt a ton of things. But we are almost there and we soon will open again the playtest branch so you can try it and give us your feedback.
As this feature took longer than what we anticipated, some others might not be in the 1.1 and will be postponed to the 1.2. We will tell you more on our discord so don't hesitate to join! https://discord.gg/xjyEBWUpes

Have fun whith this update, we can't wait to show you the next ones :)
Patchnote v1.0.15
Optimizations:
The third act has been greatly optimized and its memory usage has been divided by 5.
Other textures optimizations have been made on the second act as well.
The game now needs less memory to run and also lost 1 Go of memory disk needed for installation.
Anti cheat:
We added cheating detection to avoid having cheaters in the leaderboard. It's still experimental so we won't reset the leaderboard untill the 1.1 update. Until then, please give us your feedback in case the anti cheat detects a false positive.
Bug fixes:
Fixed a huge bug that could stuck the player forever at the start of the tutorial if the player had previously restarted the game during the first steps of the tutorial.
The screen resolution issue that reseted after each act change is now fixed.
Building more than three Tar Trap would often cause the game to crash due to a Graphic memory issue, which is now fixed. Tar Traps would globaly slow the game and are working properly.
Loading Act 3 could sometimes crash the game for the same reasons or stay stuck in the loading screen, mostly in multiplayer, which is now fixed.
The anti soft lock system has been updated and will now work differently. Instead of waiting an amount of time before auto validating the wave, it now detects stuck enemies and will kill them automatically.

Hello my dear Kritters!
Thank you for you patience and your dedication in giving us feedback to improve the game.
During the last three days since the last patch, we fixed dozens of bugs, balanced the game to ease your progression and changed a few gameplay elements to make the game more fair.
Here is a highlight of what's new :
The endless mode waves have been reworked so the difficulty of the wave 20 is equivalent to the previous wave 10. Progression will be smoother and higher waves reachable. Also, you won't find irrelevent items in endless mode.
The first boss is easier. We heard you and agree that the first boss should not be that hard.
Chests no longer throw items aways so none will be expeled from the map of fall into the ground.
The quality of the wave reward items now depend of the defense rank you get.
More than 25 bugs fixed with a lot of multiplayer ones.
I'd like to thank again each of you for all your help. As you may know, we are a tiny team of two with a unique dev, so fixing all those bugs in a short amount of time is tough.

We also understand the few negative reviews we had due to the many bugs the game had during the first week of release. But if players want to play cool indie games not made with AI, you gotta chill a little and give some time to those tiny teams to reach the full potential of their ideas before hurting them with those bad reviews.
If you have not yet joined our discord server: feel free to join to give us your feedback and discuss with us and our community so we can improve Kritter and make it even better!
Cheers,
Bastien from LJF Games
See the full patch note right bellow for more details.

Act 1 & 2 world have been cleaned of obstacles that interfere with player projectiles.
Gameplay

Endless mode waves have been reworked so the difficulty of the wave 20 is equivalent to the previous wave 10. Progression will be smoother and higher waves reachable.
The better your rank, the better your luck : C rank = same as before; B rank = +25% luck; A rank = +50% luck; S rank = +100%. Better result means better rewards.
The shop now has items with quality depending on the luck of the player. Legendary and Epic items will be found less often there.

There was an arena that didn't spawn Pierre, it's now fixed.

Fixed a bug where the inventory shown at the end of the run would not show you item details.
Fixed a bug where Alexia could dash intro the gallery.
The teleporter markers could something not be show. It should be fixed now (note that I'm not 100% sure).

The languages drop down from the settings in a run was empty. It's now fixed.

Patch 1.0.6: Loot Logic and Economic Rebalancing

👋 Hello Kritters!
We are back with another update to keep the momentum going. Following the new cloning protocols and multiplayer stability fixes, we’ve spent the last few days looking at how the game feels to play, specifically the "flow" of combat and the economy of your upgrades.
Our goal is to make every run feel smoother while ensuring that high-level upgrades feel like a true achievement. Here is what M.Ark has in store for you today:
Quality of Life & Combat Flow
Loot Sprinkles: Tired of items dropping in a single, messy pile? Treasure chests now drop items that spread out, making it much easier to see (and grab) exactly what you just found.
Seamless Combat: We’ve updated the input logic. You can now keep your primary attack held down while using another skill. Your primary attack will simply "pause" and resume automatically afterward, rather than being interrupted entirely.
Balancing & Economy
Luck of the S-Rank: Performing at your best pays off! Achieving a Rank S wave now grants a +25% luck bonus on your rewards.
Engineer Power: The Engineer now starts the run with 2 turret charges.
Upgrade Costs: To better balance the late-game economy, we’ve adjusted the Blue Crystal costs:
Carbon Drill: Upgrades now cost 35 and 50 crystals (up from 25/30).
Blue Crystal Drill: Upgrades now cost 35 and 75 crystals (up from 25/30).
Skill Tree Adjustments: * The Temporal Convector now gives 10 seconds of exploration on Level 1 (down from 15).
The gadget charge bonus on the 3rd skill tree circle has been removed.
M.Ark Level 3 no longer grants a flat 50 health bonus.
Bug Fixes
Mission Tracking: The "Kill 10k enemies" mission is now officially fixed and tracking your kills!
Challenge Fixes: "Nice Defense" and "I’m Different" are now working properly.
Ninja Mastery: Fixed a bug where killing the 2nd boss as the Ninja wasn't recorded. Note: You will need to beat him one more time to claim the "True Fans!" challenge.
UI & End of Run: Client players can now see all their stats (kills, damage taken, M.Ark damage) on the end-of-run screen. We also fixed the camp completion stats and mission pop-ups.
Act 3 Stability: Fixed a critical bug where waves would stop spawning after finding the third key.
The Final Door: You can no longer open the final boss door while a wave is actively attacking M.Ark. Focus on the defense first!
We are still ironing out the last few "pink square" visual glitches and translation issues to make the experience as polished as possible. Thank you for your continued support and for helping us make Kritter better every single day.

👋 Hello Kritters!
We are still steadily working on fixing the bugs liggering in our game, as we have been for the pas few days. We want to thank everyone again who helped us by sharing the weird behaviors and bugs they experienced on our Discord server and here on Steam.
Today’s patch continues that mission with more improvements to the multiplayer experience and some life-saving tech from M.Ark. We still have work to do to make the game perfect, but we are giving it our all!
M.Ark to the Rescue
We know how frustrating it is to get knocked out during a heated boss fight or a wave, only to find out you can't be resurrected for the next act.
M.Ark has been upgraded! Now, if a player dies during a boss fight or a wave, M.Ark will automatically clone them when everyone is teleported back to the ship. This ensures your full squad is back on their feet and ready for the next challenge without any "permanent ghost" issues.
Multiplayer Stability
To ensure everyone has a stable and fair run, it is no longer possible to join a multiplayer game that has already started. This change prevents several synchronization issues and keeps the challenge balanced for the team already on the ground.
Bug Fixes & Map Polish
Turret UI: Fixed a bug where the turret ammunition bar would stay on your screen forever. Your HUD should be much cleaner now!
Gadget Charges: Fixed an issue where client players (guests) couldn't use the correct amount of gadget charges they actually possessed.
Safety First: Added a fence to the Endless map to prevent players from accidentally falling out of the main area.
No More Lava Traps: Fixed a specific hole in a lava tile in Act 1 where players could get stuck.
Thank you again for your incredible support and patience as we polish the experience. More features, fixes, and adventures are coming soon!

👋 Hello everyone !
This is Tom and Bastien, the two developers behind Kritter: Defend Together.
The game has now been out for 72 hours, which feels a bit surreal for us after four years of working on it, just the two of us.
We've received a lot of kind messages from players enjoying the game, and that truly means a lot to us. Thank you so much for the support!
But... we’ve also received quite a few reports about bugs some of you have encountered.
And well… that part is less fun
🐞 Bug Busters at work
Please know that we’re aware of the issues and every day we’re working on fixing them. ( We are releasing a hot fix a day )
We did a lot of internal testing before release, but we clearly underestimated what happens when a game finally goes out into the wild, running on many different machines and hardware configurations.
The good news is that your reports help us track and fix issues quickly, day after day.
A huge thank you to everyone joining our Discord to report bugs and share feedback.
It helps us a lot.
🎮 About Local Co-op
Right now, Kritter: Defend Together can be played:
Solo
Online Co-op
The game WILL support local co-op, but the feature isn't finished yet.
At first we thought:
“It’s not fully ready… but let’s include it in the game anyway. For testing”
That turned out to be a mistake on our part.
We will re-introduce the final version of local co-op in version 1.1, which will arrive soon.

This is the first time we’ve released a game commercially, and there’s a lot to handle with our four small hands.
Sometimes we’ll make mistakes, but please know that we’re committed to fixing them all over time. If you encounter any issues, please let us know in the discussions or reviews. Don't hesitate to join our Discord server too. Your reports help us fix things faster!

Thank you again for your support. More features, fixes, and adventures are coming soon!
Bastien & Tom

Patch notes 1.0.1-1.0.2
Hey Kritters! First of all, a huge thank you to everyone who jumped into the 1.0 release yesterday. Seeing you defend M.Ark and tackle the new Act 3 content has been incredible! While you were fighting for survival, we were monitoring your runs and feedback. Today, we are pushing
Hey Kritters!
First of all, a huge thank you to everyone who jumped into the 1.0 release yesterday. Seeing you defend M.Ark and tackle the new Act 3 content has been incredible!
While you were fighting for survival, we were monitoring your runs and feedback. Today, we are pushing a quick update to refine the experience, balance some over-performing classes, and squash those early release bugs.
Gameplay & Graphics
Faster Navigation: We added dozens of waypoints in Acts 2 and 3 to make returning to M.Ark much smoother. Less walking, more defending!
Act 3 Visuals: The third act just got a fresh coat of paint. Graphics have been upgraded to make the final push feel even more epic.
Balancing
The Kritters We noticed some classes were a bit too safe or powerful. We are tuning them to keep the challenge alive:
Ninja: Slight reduction in main attack (35 to 30) and Kunai damage (50 to 45). Scarecrow CD is now 10s, and backstab damage is slightly lowered to 125%.
Defender: Shield CD increased to 12s, and gadget duration upgrades have been reduced by 50%.
Tracker: Landmine CD increased from 5s to 8s.
Engineer: Turret projectile upgrades now add 3 projectiles (down from 5) to prevent total screen-wipe too early!
The Bosses Some of our big bads needed more "oomph" to match your skill levels:
Pepe Rocky: Move speed increased (12 to 16). No more easy kiting!
Alexia & Cyril: Health increased by 30%.
Elen Mask: A significant buff for our favorite tech mogul. Health up by 25%, armor increased to 200, and damage boosted by 20%.
Items & Defense
Easy Opening: Now Epic rarity. Damage bonus adjusted to 2%.
Power Nap: Now Rare (remains Unique).
Act 3 Wave 4: We felt this wave was a bit too quiet. It is now significantly harder. Watch your back!
Bug Fixes
Leaderboards: Run timers are now correctly uploading. Time to prove who is the fastest!
Pepe Rocky: Fixed his missing whirl telegraph and the achievement bug.
Megalomania: This achievement is now working properly.
Turrets: Fixed bugs where ammunition stacked exponentially, didn't display correctly, or fired at targets out of range. Client players can now see their own turret ammo.
Act 2 Bosses: They no longer drop two nuclear cores (which was breaking quest progression).
Narrative: Fixed the final boss death dialogue and various translation issues.
Level Design: No more getting stuck in that specific hole in Act 2.
Thank you for your patience and your reports! Keep the feedback coming in the Discord and Steam, and good luck with those Act 3 runs. Also, here is a reminder of the roadmap we will be following:
See you,
Tom & Bastien, LJF Games

4 Years, 2 Friends, and a Dream
This isn't just a game launch for us; it’s the culmination of a 20-year friendship. Tom and I (Bastien) started this journey in 2020 during the pandemic. From funding hurdles to marketing marathons, we’ve seen it all.
We recently shared our full story in a "4-Year Recap" video. It’s already hit 12k views, and we’d love for you to check out the journey behind the chaos: 📺 Watch: The Story of LJF Games

What’s New in the Next Fest Demo?
We aren't holding anything back. The demo is bigger, faster, and more polished than ever with some of the content from our creator beta added to its content:
