Interesting game, I'd say you made a good job making this one, really the level design got me thinking and had me using my brain, only thing I didn't like is the small bounce since that would make me fall, but at least I respawn instantly compensates for it, so it's more working around that. 
well that and the fact that, spoiler alert, there's no ending... it just ends... but overall it's a well controlling and well thought out game.
