The action game Slice It All is very interesting. Tap your knife to make it spin, and then carefully cut each obstacle in half. This is the best way to make a slice that is just right.
You can do anything with a sharp knife. If you flip the knife at the right time, you can cut pencils, pipes, anvils, and other things. You will have to stop running if you touch the water. Try to get to the dark gray boards that mark the checkpoints.
