Oh wow this was a ton of fun! Music was a bop and the animations worked really well, really enjoyed the amount of puzzles that there were for a game jam game. The idea of needing to pop all the slimes, while not "losing" any of them by dropping them into a pit is a really fun twist that I enjoyed puzzling through.
There are a few small polish related things that I think could bring up the sickness even more, but I totally understand why they're not here in a game jam game.
- Having an animation state that conveys how many hits a slime has taken (or has left).
- A little indicator of where you will land when you move (or where you just were) would be a nice toggle.
- Some sort of post-screen that shows how many moves it took you to beat the level would be a fun way to challenge yourself with solutions.
