You play as the submarine, so use the Arrow keys to move. Avoid the Octopuses or the game will end; when the game ends, click the green flag again to try again. Main Goal: Catch the Coin as many times as possible and beat the High Score! :-D
I used basic operator functions to get the sub to move with the arrow keys. The game is very challenging so beating the high score is gonna be an achievement. See if you can beat the High Score!
