This is definitely a game with a lot of potential. I really like the partnering mechanics and using each others strengths to get to the end. However each level feels more like design prototypes on how mechanics can be used, then actual level with design mechanics build in. To me this feels more like a time constraint by the game jam.
What I think would have helped a lot is by making 2/3 levels that are much bigger and implementing multiple mechanics at the same time.
The art style furthermore is simple and cutesy.
At last there is a bug where the music cuts out after a couple of seconds of playing. And the controls don't function properly. Using the left and right arrow works the same as A and D. but up and down don't make it jump or disembark. Furthermore occasionally after embarking, my immediate left/right input gets eaten.
