Very impressive, for a game jam! I had fun playing (up until the stones, which I died 30 times and gave up). The scenario was SUPER cool. Well done!
A few feedbacks, if I may:
1. If you wont have time to make the controls very snappy (coyote time, jump buffer, good camera, etc), avoid difficult platforming , which can be frustrating
2. In a game about squizzing in into tiny spaces, make sure there are no gaps in places not meant to be secrets (I got stuck inside the pagoda behind the key girl, thinking it was a secret)
3. I more cartoonish setting would have been great imo, since I found all the model scretching very funny and unserious
