Defend the moon from enemy spaceships! Use left and right arrow keys or A and D to control your red character at the bottom of the screen. Shoot the space ships with your yellow lasers. Try to beat my record of 649!
Thanks to @OmegaPokemonOP for suggesting the game. The score variable is calculated by multiplying the number of spaceships destroyed by three and then adding the number in the 'time' variable. For instance, if the player had destroyed 11 ships and had survived for 8 seconds, their score would be 41, since (11x3)+8=41.
