The art style is very cute, the sound is great and I personally think it was a great idea to give no instructions whatsoever! Even if, yeah, probably not the best idea in a game jam where people most likely will play your game for 2 minutes, not understand anything and move on >.<
I’m not sure I can say I understood the game, but I sure made progress! I think it’s a very unique idea, or at least I haven’t seen it done anywhere else. I can definitely see the sort of puzzles that show up with these mechanics you’ve created, so all I have to say is
Good job!!
