Fantastic animation work on the main character. While movement is awfully slippery and sometimes unexpectedly restrictive with when you can do a given thing or not (jump from dash, coyote time on the jump), everything feels like it comes together really well when you hit the right flow. Some more polish and extended level design would probably make it a lot easier for players to tap into this appeal. Sound effects especially would support the movement well.
Now and then I'd have a problem with the camera direction just flipping over to somewhere else. I don't know what would cause it while playing KB+M, but it is rather jarring. The floors that send you flying back feel like they acted a bit inconsistent with where you would go.
Overall, very tasty sauce! Could benefit from some seasoning and like... some pasta or bread or something to put it on. Keep on cookin'!
