Thank you for your incredible support! As of today, our sales have almost reached 10,000 copies!
For a fully independent team of just five developers, this means the world to us.
At the same time, we’ve received a huge amount of valuable feedback from you — most of it focused on:
Performance issues in the game
Early-stage difficulty and balance problems
UI guidance and configurable settings
We sincerely apologize for all frustrating experiences
We promise we’re working hard to deliver the best
Based on your feedback and our designers’ research, we’ve been working around the clock — pushing 4 major updates in just 48 hours, with 22 feature improvements and 9 bug fixes, including:
Significantly reduced memory usage and package size, and major performance optimizations.
Adjusted early-stage levels and the first mech’s balance, allowing players to unlock and enjoy later normal-difficulty content faster.
Improved mission prompts and operation tips to help new survivors get through the early game more easily.
Major upgrades to Tower Defense builds — faster deployment, shorter cooldowns, and healing towers now repair nearby defenses. We’ll continue refining Tower Defense and other build-based combat!
Added toggles for damage numbers and controller vibration, and enhanced the range indicators and projectile visuals so you can keep better track of combat even in late-game chaos.
Thanks to these updates, the gameplay experience is already much better than at launch — but we know we’re still far from perfect, and we’re not stopping here.
Next, we’ll continue optimizing the game, including better controller support, clearer map objectives, and improved tower deployment controls. We’ll also keep expanding the game’s content to bring you even more to explore!
Thank you again for standing with us!
If you have any thoughts or suggestions regarding future content updates, we warmly invite you to participate in our survey. Your feedback will help us deliver better game content for everyone.
