I really love this concept! The game feel is really nice, the momentum is great. However the level design is quite strict. Also a tip, I would make the button for launching the same a jumping because it is kind of the similar action and it doesn't interfere with the controls. Also the timing for launching is a bit strict but I love the physics. I would love if you expand this game concept to include more free flowing levels and bouncing on enemies. Great job man!!
