You've rigged this rudimentary puzzle toy into a weapon to be used against none other than YOURSELF whenever you venture into your UNDERGROUND HALL TRAPS.
Moving the sides will, in turn, rotate the various walls of the expansive room at different angles — each leading to passageways that house a wide plethora of rigged devices that lie in wait for you, ready to unleash chaos on your ass. The goal is always the same, though: to reach your BELOVED HENTAI DUNGEON.
