Click "Play" to play. Use up arrow, space key, or left click to move the wave up, and let go to move the wave down. Avoid red, orange is a place for the wave to slide. The purple/blue portal turns the wave to have more vertical motion. The light green/dark green portal turns the wave to have normal vertical motion. Press the "n" key to activate no-clip (be able to not die).
