Press a number on your keyboard and then make some sound. Depending on the volume of the sound, the block(s) with the corresponding number on them will go up higher. The blue blocks can be stood on, don't touch red, and get to purple to win. Press space to drop the player in, WASD/arrows to move, and "R" to restart. I hope this inspires someone!
This does require microphone, so sorry if your computer doesn't have a built-in one. This is a concept, not a game. If you would like to make it into game, leave a suggestion or remix this project. Since this is only a concept, I didn't spend too long on the physics, so I know the gravity isn't very good. I want to thank @PullJosh because his challenge #1 (audio visualizer) inspired me to make this. All programming and art (as minimal as it is) is by me.
