Press space to start the game. Hit the purple frog with the up arrow, the red frog with the left arrow, the blue frog with the down arrow, and the yellow frog with the right arrow.
I made a version of ACM's project whack-a-frog so that it can be used with the front side of the makey makey. I also added difficulty levels. Full credit goes to ACM for the rest of the project.
