Use the arrow keys to move. Use space to shoot. Don't get hit by bugs, and don't let them get to the bottom. Shoot the ufo to get a power up. There are more bugs the longer you play. Once you get to lvl 10 then you get to the boss!! Take down all his shields and kill him to win!! Have fun!! ;) This may only work if you press the green flag more than once. Press L to see the leaderboard.
