Echo is a simple game played with only 5 keys. Use the F, J, R, and U keys to control the sounds. Spacebar begins the game.
Once the game begins, the computer will play a simple sequence of 2 sounds. It's then your turn to match the sequence. If correct, the computer then makes the sequency slightly more complicated. Then it's your turn to echo again, and so on.
