Love the art you've done, I can see why you didn't have time to finish, its so detailed! I like the concept of having to be careful about how long it takes to kill enemies and which to focus on. If the enemies ticked up over time and would be paused when hit instead of increase the other enemies health, I think itd be an interesting action puzzle platformer or something, chasing after enemies trying to decide who to target and trying not to let their health balloon. Youve got a great concept here!
