Levers is another Flash game done by Vector Park, of which I've mentioned a couple of times on this Blog. Levers doesn't actually have defined goals, it takes a bit of time to figure out what the game is about. There are no points, or levels or prizes. You kind of just... Play along.
The basic idea is to try to balance everything without letting anything touch the water. If you manage to balance everything for about 5 seconds, you'll get another item and you'll have to figure out how to balance it.
I couldn't make it past God's Head, let me know if you manage somehow.
