This game has well crafted levels with clear and simple controls that still holds the potential for so much depth. The shader work is impressive without being too flashy, it's there to do a real job and it does it so well.
This should be made into a room-by-room based Celeste-esque game with quick retries.
I think the biggest strengths of these mechanics is pulling off several difficult moves in a row, where you can show off your range in level design skills and allow the player to experiment without having them worry about losing progress.
I repeat: go for a more fluid and flexible version of Celeste/Super Meat Boy/etc.., with a single (or two at most) additional core mechanic to be revealed later, and you have a winner on your hands. A game with a feasible development scope that you can work on in chunks. I know I'm going to love it, at least.
Seriously, great work!
