on the second level "outskirts" you can find a skull on the top of the building in the beggining of the level, if you follow the way throught he blinking light, then turn around, you'll see the light you can jump up their then turn to the right and jump up there. Follow down a dark area and you'll see a skull and it makes your "blind" if you pick it up. Anyone else know about these, and if there on different levels? I also noticed that its harder to die like that, maybe cause i was playing on easy to find it, who knows.
