The get to the Ufos: press space and take your points from generation and size to raise speed and boost.
I don't like the controls, they're not precise since I'm just circling my mouse, getting stuck with my cursor by getting out of the game's frame and loosing. I couldn't beat wave 50 after more than 1 hour trying to do so. You have to kill the aliens first und even if this wave is intended to kill you: I would like to beat the game. I wasn't able to upgrade anything 'useful' any more, armor, size, etc. were all maxed. If you add some points to health, it would be very nice.
I liked the artword, the soundtrack could be more intensive, different, the controls are a shame and I would have liked a more vivid sea ground.
