I like the idea and theme, music works well, visuals are ok, pretty simple but could be improved quite easily, the levels seem very hard though, maybe I just suck a lot but it felt like every level had one if not more areas where you needed to take a hit in order to pass through, was that really the case or do I just suck the much xD.
Overall nice entry, maybe some tweaks to the difficulty but very complete otherwise, good work!
