[Made in 1.4] Flash should work, but downloading in scratch1.4 definitely works: 0 glitches no doubt. Note: 5 levels: 3 easy, and 2 are a little harder.
Instructions: Clap your hands hard enough to make a loud sound or say something like "Jump" loud enough to make the guy jump. Reach the door in each level to win. This is made off my project Mbees (May be useful for the future)- Sound Jump Test. ( http://scratch.mit.edu/projects/2303939/ ) This is a "Sound Platformer" meaning that you have to use sound in order for parts of this platformer to work (for the guy to jump). That's all enjoy! Note: This is one of my "small project's", but I think the idea ("Sound") made it turn out actually fun. Enjoy :D! Note: The project is winnable
