Pretty basic survivor-like, but it works well. My 2 grievances are:
- Why limit the time you have to select a mutation? I don't see what it does for game feel, except add frustration
- It seems that your screen shake adds up, and as you get more abilities and there are more and more enemies, in the end the screen is constantly shaking and it hurts my head x)
Other than that, I think it's pretty good. The sprites are nice. I'm not sure what biomass is used for, I was getting more and more and couldn't see any way to spend it.
