I got about 250k points, hoping that there would be some more upgrades after rapid-fire tri-shot gun, but it seems not to be the case.
The game is ok, I'd make the rotation not so sensitive, cause often you can't get the right angle to destroy your target, and I would also make the asteroids white, cause right now they're very hard to see. Maybe also add some extra content, cause right now I see no point in coming back to the game.
