Hey. Congrats on submitting! Quite nice platformer controller, works well with the level design - no jumps were hard or frustrating.
One simple thing you could to do improve the UX would be to use Camera properties - Position Smoothing and Drag. Try it out and it should make the gameplay feel much smoother.
If you can, you should include at least a windows version, as that's what most people used.
Cheers!
