Nice! Overall things played great!
I really liked the level design, and there were some cool obstacles to get around.
The things I would try to improve are the visuals -- and I don't mean the graphics, I mean more of the visual state of the game. I figured out there are two movesets basically that you need to traverse the level. It would be great to communicate what those modes are. When I'm in each mode, and what it means for me. So for example, I think the white diamonds only matter for the 2nd moveset, right? Having those show up only on the 2nd runthrough would be great. And when I can climb walls, maybe some kind of shoes that make me look like I can wall climb.
