pretty nice idea! Took me a bit to understand how to upgrade /buy properly. But didn't make it past the level with all of the monsters coming in.. is that one winnable? I also think it could have been a bit more clear how the ui works. Good job :)
The 60 monsters wave is definitely winnable. However, some ultra end-game waves haven’t been thoroughly tested. I’ll scale down some of those.
Additionally, I’ll be buffing certain morphs to make them more viable.
Thank you for your feedback!
