Good game, I like the art style. However, it looked like the character was kind of flying, or climbing the background - it didn't look flat, but rather like a wall. The main mechanics were quite fun, but a bit underpowered. I would also have liked to be able to pick up health boosts in some way so that it wouldn't be so hard if I accidentally got hit some time. One last remark, the enemies would sometimes shoot me when I couldn't see them, which is something I dislike as I could do little about it.
