Nice game! Some jumps were really tricky, but didn't feel undoable.
I found the controls a bit floaty, but I think that was mainly because of when you land, you can still slide a bit. I think that when you stand still immediately after you land, it would feel a lot tighter.
The tileset is very small and repetitive, but I actually like that a lot. It gives the game a sort of retro vibe.
