The trippy effects are really nice, but I think it's a bad fit for a platformer. The first 2 lvs are fine, the 3rd one is a tad tedious and the final one is just an exercise in frustration.
On top of that, the char controller is super slidy. I saw a comment below saying you were going for an SMB feel, but from what I remember, it wasn't that crazy even when sprinting.
Also I don't there's any coyote time or it's super short. To be fair the controls are very consistent and their some snapping to platforms too.
My second time took slightly below 3 mins. I'm not gonna talk about my 1st try...
