Not a bad start but the movement definitely needs some adjustments. I'm guessing it's velocity based? Because it seems you can move very quickly diagonally but left/right and up/down is like a crawl. I also think you could use some sort of story, even a simple one, to explain things. For instance, who am I playing as? Why are they here? What is their goal, and who are these horned creatures with clubs trying to stop me? These are the kinds of things its good to start thinking of early on when coming up with the idea. Also, I'm not sure if its a bug or you just didn't get around to making a third level but after beating level 2 the button for next level doesn't work :(
