The Haunted Castle

You search a castle of 11 levels, each a grid of 10 by 10 rooms, for three hidden treasures, at most one on any level. Each time you walk into a room its doors are dealt again: between one and three of its open sides close behind brown doors, so the door you came in by can slam shut behind you. Stairs join each level to the next. A ghost waits in about one room in four, slower than you but relentless. If it catches you with no treasure the game is over; if you carry treasure, it takes one and hides it again on a level that has none. A map of the rooms you have seen on the current level helps you find your way. Bring all three treasures back to room 00 on level 0 to win.

Controls: Use either joystick. The stick walks; the right button shows the castle map of the current level; the left button starts. On the title, left and right choose START or CREDITS.
