I like this one, the movement is slippery enough to feel good whilst also not throwing boxy off of ledges. generally I felt minimal (if not zero) frustration when playing, which is good because not all platformers have to be pin-point precise and I liked the calmer nature of the game.
If you really did only use two days to work on this, I think you did amazing for the time you had! It takes a lot of effort to design levels and make the main character smooth to play as, especially in 3d, and I personally think that you managed to succeed in those regards.
I really believe you should work on this further after the jam for fun. Great Job!
