Fun, clever, simple and interesting! Challenging levels and fine game play. This could be a real game for mechanics, just need some more levels and game save points.
This might work well on the mobile platforms too, while the player are able to dash with the double-tapping screen. Also maybe 10 hitpoints and after that player has wait for more, or watch an advert... I hope you do improve these graphics too, while these are still very good graphics for game jam graphics. Good and working concept indeed.
