Press generate to make a random terrain. Press save to get a save code. Press Import to load a save code. Flick the 'bob' switch to toggle bobbing. Clicking the terrain will cause 'explosions' in the terrain.
By the way, if you type 'none' into the import section, it will give you a random terrain! This is all by me. I was inspired by a featured project though. I have taken no graphics or code from anyone.
