Well done on finishing your first game jam, and it's awesome that you are your partner worked on this :D
The character is simple but super cute, so you gain some points there. The central mechanic of the game is a little arbitrary for my taste and I felt a little bit too much like I had to guess what the designer was thinking rather than relying on comprehension of mechanics.
The idea suits the theme, but to a fault. I feel that with some feedback that provides the player with the means to determine dangers ahead of time, it might feel more fair/fun.
Bonus points for making a jump that responds to the length of input - this is the kinda thing a newcomer would miss!
