It seems to be able , to sometimes pass through thin walls (Bug?)
It is very similar to the Ninja Rope, but much more advanced. It's quicker and easier to use.
The Teleport Gun appears as a ray gun, and when you press Space, it fires a beam that instantly teleports you to whatever surface it hits. For example, if you fire it at a wall, you will teleport to the wall when the beam hits it.
It does not end your turn, just like the classic Ninja Rope.
It is also useful for reaching high places without ending your turn, as you can use the Teleport Gun instead of the normal Teleport without ending your turn.
