The model is cute but the animations felt somewhat... off?
Besides that, the movement concepts are great but need a lot of work and polish; they currently feel inconsistent and clunky at times, which are fatal flaws for precision platformers. It was also pretty frustrating to fall down all the way when doing a single mistake and having to go back all the way.
I think this is a good foundation of a game and definitely appropriate for a game jam prototype. Good job!
