Sticks (walls) of any color according to the image, 1 adventurer in each player’s left corner, 1 monster and 1 disc (treasure) per player in the closest center square.
Up/down/left/right
Move your adventurer 1 square in the direction AND the monster of the same color in the opposite direction (if not blocked by a wall or a piece of similar type). Check Encounters for what happens with pieces of different types.
Left button
Pick up any 1 treasure in your square. You may only carry 1 treasure.
Right button
Use 1 carried treasure to discard all orthogonally adjacent monsters (if not blocked by a wall). Unfortunately the treasure is lost and returned to its start square.
Encounters
If a monster moves to an adventurer or vice versa, the player restarts at her corner and the monster at its center square. If a monster moves to a treasure, the monster restarts at its center square with the treasure.
Goal
The first player to return to her corner with any treasure wins.
