Don't click this link.

Don't do it. That is, unless you have an hour or more to kill. The link takes you to a very addictive and simple puzzle game written in html and javascript. The objective of the game is to progress from screen to screen. That's it. Find a way to get to the next screen. I spent an hour last night going the first 8 levels and believe me, I'll be trying to get to level 9 again when I have time. It's addictive. You've been warned.
