good start to a game

This is a decent little flash game but you need to expand it to make it into something I would really want to play on a regular basis. I think it would be a good idea to make several levels and allow for upgrades to your spaceman. I am actually thinking that you could go a couple of ways with this game. One way is adding levels with upgrades. The other is adding upgrades and doing a distance measure or exploded rocket count within a time limit. Just a thought.
