it definitely has potential! i've only been able to see three levels (I'm not very good at platformers), but the level design is interesting and the mechanics feel satisfying. i'm not sure if you've included ways to gain new powers, but that would be a great way of giving the player a sense of progress and variety. my other suggestion would be checkpoints, so you don't have to restart every time you die. it's easy for lousy players like me to get discouraged when they have to keep doing levels over again. graphically, it's sparse, but personally, I like that aesthetic. :-)
