Nice, pretty slick platforming with some hiccups as others have said. I agree that the wall jump feels a bit tight to pull off. A lot of the level sections look like it would be perfect to wall kick your way up but the way the walls are spaced makes it really tedious, and gravity is so high that it is really punishing to try and climb.
That being said I think this is really cool in concept. I enjoyed playing through the levels twice and checking out the different path options, but it gets really challenging on the 3rd loop. This would be super fun if the platforming were just a bit more polished, it would be cool to see how far you could get and how fast you can complete each loop.
Seriously good start though, most of these complaints boil down to changing a few variables until everything feels right, so this is on track to be really fun
