This was a creative use of one button to make a game that is quite sophisticated. I played the first couple of levels and it is a hard game but lots of fun. It feels more like a puzzle game than a platformer in the sense that it seems like the level design is more about planning out your route first and then trying to execute it. 

The art and sound are fantastic and really add the polish to this game. 

I don't have a ton of constructive feedback cause this was really well done. I think having a few simpler levels to start as "tutorial" type that show the player the abilities of their character could be nice. For example I didn't realize immediately that any wall reset my double jump. Super great game overall!
