Love the art style, pleasantly surprised how much of a difference the variations in colour palette make.
I got down to 0hp, but didn’t die, which was a little confusing?
Eventually hit an erorr:
Error
game.lua:148: attempt to index a nil value
Traceback
[love "callbacks.lua"]:228: in function 'handler'
game.lua:148: in function 'attempt_to_evolve'

Overall very enjoyable though, great work!
