A very competent SMB type game, well done. I like the choice of cute mascot. I beat all the levels, and I think the variety and difficulty were just right for a jam. The music was relaxing and a good fit for the genre as well; did you compose it? There's also a level of polish to the UI here that really makes a difference for the better.
I am not sure if I liked the way the camera behaved, I think the immediate effect on the camera's rotation to the map's tilting response was a bit too sensitive and got me moving in a circle when I didn't want to. I also think the general movement sensitivity was a bit too much, I never felt like I had to use the full range of my thumbstick.
Overall, well done!
