Thanks for rating my game! c:
I like your game as well! Feel like there's potential for interesting mechanics. I like how the enemies don't immediately harm you if they touch you. I also think it's neat how you can lose both hearts and heart containers.
I ended up with a lot of slime on the floor at one point. I think it'd be interesting if you could do something with that. Maybe instead of always growing whenever you get slime, maybe the only way to grow/get a new heart container is by avoiding the slime pick ups and pushing them together to form a large pickup? I love mechanics that recontextualize existing elements of the game.
Anyways, cheers!
