I love the style to death.
There are, however, a few bugs in my opinion. The major one I noticed (this could be intentional) was that on the second planet if you died, the bombs would re-appear, allowing you to pretty much blast through the whole level without using key cards. A save function would be nice also, since every time I had accidentally made an error I had to refresh the page to restart the level as a whole. The game and it's music were pretty fantastic as a whole, there are just a few changes I'd like to see. Perhaps I'm just being picky.
