Walkthrough to Level 108: Go up the stairs, go into the room. It will be empty. So use your iPad to doodle a ying yang sign on the drawing app, then submit, your ying yang sign will appear, go through it, everything will be inverted. Then open the door that is now in the room, to the next lvl.
Johno, that one's easy. See the two mirrors? Use your lazer so that it's bounces off both the mirrors, eventually, if it goes long enough, it'll burn a hole in one of them, jump through that hole to go to the other world.
