Monster Mover - A puzzle game. Get the good monsters in the portal using gravity and the removal of elements from the screen. Most of it is pretty easy, but the last level is devious. The one gripe I had is that it was difficult to tell what level I was on, and I had no indication how far I'd progressed in the game. I'll spare you that and tell you that there are 20 levels, and the web is the last one.
