It's a good game so far, but I'd have to say that it should have a few more power-ups, you should still be able to shoot from your ship after picking up the wave gun and rocket launcher, increases the difficulty as the game goes on, and provide some variety for the enemies. Also, provide a shop or an extra life for collecting these coins otherwise, you really don't need them. But other than that, it's a pretty decent time-killer game and I enjoyed it.

well nice time waster

Is it normal that there is only one level and then it continues endlessly?
Anyway, game is working so far but needs a bit more variety.
