Experiment 003

You are the box that moves.

The archers (green boxes on the compass points of the tower) are amazing, they always hit their target. However, they are lazy and need you to bring them arrows.

In the center of the tower is a flashing teleporter that will take you outside of the tower. The flashing teleporters outside of the tower will return you to the tower.

Northwest of the tower's center is an arrow bucket. It will always give you enough arrows to have 3, but never more than 3.

Teleport outside of the tower to pick up arrows, there is no limit to how many you can carry out there.

Take the arrows to the archers so they can continue to shot at enemies.
