If you've got some time on your hands, play this game. It's very interesting. If you don't have time, then don't start the game. I managed to get through all 100 levels, but I had to cheat on about 10 or so. Out those ten there were maybe 5 where I had the picture drawn perfectly, but couldn't guess the right word for the answer and another 5 that I never would have gotten. It's very satisfying to see the pictures and get the answers. Just go through the tutorial (about 30 seconds) and it will make perfect sense. On those few you're going to go crazy on, use the walkthrough. Click the part that says "spoiler" to open the walkthtough.
I took the game down because it seemed to be screwing with the page. Also that music sucked. But you can search for z-rox and play it somewhere if you're still into it.
