I like this game even though the controls are a bit imprecise. Since I don't know how to exit the game, I play it in window mode. I can't see the whole screen. When I start the game I don't see the ship. I have to fly into the screen from the left. The left of the 5 cubes is not shown to me, the 4th is only half shown. Is this intentional?I've only been playing the game for a few days. My best result is 1997.
