Taking a little rest from trying to build an inventory script, I built this logic maze. Unlike many game mazes, it has certain "rules" and is not just wandering about until you find a door.
Although this at first may seem rather odd, think about trying to drive in the centre of a busy city that has signs saying no right turn, no left turn and one-way streets - all "rules" you have to obey to get to your destination - or you get a ticket!
There are 15 "plasma gates" to navigate though you only need to go through 10 to succeed (and two of those are repeats).

Hope you enjoy it.
