WASD to move, SHIFT to sprint
1 - Keep the skull with you, or don't walk too far from the skull, the line on your screen shows your distance with it
2 - Hide the skull in a room when it's awake (NOT ROOMS WITH CANDLE inside, they are cursed). It will reset when you do so, pick it up and keep exploring after.
3 - Run if you put the skull in a curse room. ( But you'll die if you run too far)
4 - Find a way out, the key is in one of those rooms.
