Use arrow keys to move, space to get a boost while going forward, and q to shoot bullets at the enemies to get a higher score. Do not touch the enemies, and touch the small whitish boxes to get 50 more ammo. The larger orange boxes are lava, and you need 100 score to win the game. Fun fact: The chance of any two enemies being exactly the same is 1 in every 4.88 trillion or a 0.00000000000204918% chance.
