I think the biggest thing wrong with this is how you are basically just in the same spot. I think there should be more variety. I do have to admit it is kind of cool with the enemies. I can't get rid of most of the bombs. I think this would have worked more as a standard platformer. The jumping's still pretty good.
You get the hang of it pretty quickly. I like how you mixed it up with different enemies who all have different ways they moved. I can't help but think you took the name from the Marvel character. He's pretty well known. Still a decent game.
