I like where this is going. A couple things I noticed though. Looks like an attack sprite is missing? When I attack, I am getting an opaque white box in front of the player. Also, I got stuck not too far in (where the level drops down, then s-curves up and to the right) as the jump height is low and couldn't reach the middle. One thing I do like is that it has a level-up mechanic where you pick your upgrade. Keep it going. Good work so far.
