This is probably one of the more finished feeling games I've played so far. Everything is very well presented and functional. I guess if you're going to be polishing up, you might focus on the graphics. They're certainly passable, but not quite the "iPhone" quality the rest of the game lives up to you. I also have a slight quibble about the collectible stars... somehow they felt unnecessary seemed to slow the pacing down considerably, but I still agree that there should be some kind of collectible. Perhaps if the stars tended to appear in the space in between planets rather than tending on the surface of the planets themselves, that would be an improvement.
