In this two player game there are two rockets, Player 1 is green coloured Rocket and Player 2 is blue coloured rocket. If you are player number 1, then press the WASD letters to move player 1 , and if you are playing as player 2 then press the arrow keys to move player 2. If player 1 touches player 2's light blue line released by Player 2 then player 1 loses and player 2 wins,and if player 2 touches player 1's green colour released by Player 1 then player 2 loses and player 1 wins. You can also play it in single player but it would be tricky to press both of the keys. Green Flag+Shift=Hard Mode
