The art, animation and overall atmosphere looks like children's book, very lovely.
The music fits the game very well.
The mechanics take a bit of time to get the hang of it, but once you understood, it gets a lot easier.
The puzzles are well thought, didn't feel repetitive at any moment.
Perfect use of the jam theme.
The first mouse instruction seems like it's telling you to right click instead of left click to inhale, I got a bit confused at that part, took me some time to figure out.
There was a missing sprite in the snake level, it might soft lock people that don't read your warning, but you are already aware of it (hence the warning).
Overall it was a great submission, congrats to the team!
