Once start is pressed use the space button to begin, and use arrow keys to move. "Bob" the platform progressively grows smaller, but denser when you jump on him. My P.R (Personal record) is 30, try and beat me ;) Every 10 seconds, something MAGICAL will happen. BTW if you find the brightly changing colors annoying... they're supposed to be. Remember... J UST BOUNCE!
Credit, and thanks to Scratch Wiki for the basic velocity, gravity, and max speed code. I started by making a platformer with their "Basic Platformer Code" and then added "Spikes", "Weird ball thing?" "Laser" and "Bob"(the platform) again thanks to Scratch Wiki for helping me get started.
