You love to hate this game, eventually :D
I always enjoyed these games, and it works as intended, although the ship somethimes turns on its on, except for that I didn't notice any other weird things.
Graphics can be improved a bit, with a little background and some music but that's a minor point and didn't matter that much for this game.
Overall a good (frustrating, by design) fun game and fit the theme well, good job :D
