Pretty fun game! The platforming is nice and responsive, and the level design is good. If I'm being critical, the arrows are a bit hard to see at times, I would consider giving them some more contrast, or outlining them or something. Also it would be nice if I could have one jump if I leave a platform without jumping, since to me that's usually how double jumps work. Other than that, I have to say this is a very polished game, nice job!
