As with most 'clicker' games, after about the third tier of upgrades, clicking is kinda pointless. And the cost for parts rises too fast for high numbers.... the 100th Beam, for example... Go watch a movie waiting for that. The graphics were pretty simple, which is fine for this sorta game. Though I was slightly disapointed when the stars in the background didn't change. The jokes were enough to keep me playing, but seemed to use up most of the funny early on. Music was pretty decent, but got very old... mostly because of listening to it for so long.
