Here is a fun arcade game where you have to shout to go up, and be silent to go down. Try to avoid the green walls, the missiles, and the spiky traps. P.S. If anybody thinks you're weird because you're screaming at your computer, just ignore them.
Everything is by me. There is no music because that would mess up the game (you'll see what I mean once you start playing). It uses the loudness block to sense how loud you are.
