There are 6 whole levels of putty challenge in game to play now! An in game level editor and a walk through tutorial. Go on, give it a go!

You can either Webstart it or play it as a slightly beta LWJGL Applet

Look out for the bonus typos. Please note the game is still very much a work in progress, there will be plenty of bugs.

EDIT: There's a new pure Java applet available, it's much smaller and is probably more compatible for running in the browser.
