Remix and add yourself. ;-) It's just something to do. Here's how you add more bouncy things: Press (or hold) space to spawn another ball. Press (or hold) w to spawn a worm. Press (or hold) b to spawn a bomb. If I sense something wrong in your remix, then I'll remix it and fix it. ;-)
I added a "pop" sound to Yellowbross, since everyone is doing a "popping up" action, so might as well do it to Yellowbross. Added some scripts. C2A. :-)
