A timekiller. First of all, the player needs to light his way, and then make a decision. The monochrome color scheme and oppressive music create an unsettling atmosphere (at least that's what it was intended to be). You are a demon from the underworld. Consume the souls of the dead. Collect torches to light your way. Dodge obstacles. If you have 0 souls or 0 lives, then you will lose.
