Simple, a bit too much maybe. There's not much going on, except going through the level as fast as possible. The controls are fine, but the jetpack doesn't activate sometimes when I walk. Also, if you rush trough the level (which you have to do if you want to stay alive) the bombs are useless. I don't really get the link with the theme, except with the life bar. it would have been more interesting to use it as another mechanic rather than a constraint, if you see what I mean. But apart from that, nice job :)
