This is incredible! The art, characters and story are all very well done. This jam has quite a few games where you get to play as multiple characters and I'm really enjoying it! In yours, I particularly like the fact that the characters can interact with each other to solve puzzles.
My favorite part of the game was the puzzles. You added a lot of variety which made puzzle solving a delight. I felt engaged throughout the game.
I'm trying to think of how you could make an improvement, but honestly can't think of anything. It was pretty much perfect for me. Well done!
