The art of your game is very polish, I like the contrast with the cuteness and the monters in your universe. There is definitelly a big potential with this.
I wish there was a bit more indication on what the player have to do. I got stuck after putting the box in the vortex. Because of the theme of the jam, a lot of people created "unfair" games by putting random trap here and there. Creating unbalance game and sacrificing player's pleasure.
It's too bad, because I was quite enjoying your game, until I got frustrated because I could'nt finish ^^"
The control feel a bit stiff, when jumping the bear feel pretty heavy
Overhall great art, audio, and great universe, congrats !
