Tested Windows version. Works okay, but I had a funny flaw in my test run. It broke the Gimp Universe and my brain boiled over.
The entrance was set to west, and the exit east but the exit appeared in the M letter. Now Wilber is trapped and running out of paint!
Did you know that he needs to consume 3 big buckets of R, G and B daily to keep the Gim'dom vivid and bright with his brush?
So I contacted the Gimptelligence Bureau Executive immediately, and he confirmed that there has been some kind of on-the-fly intervention during the creation of Magic Maze-5 compound. They can't reveal much at this point, due to the supernatural aspect of he incidence. Wilber's arch enemy presumably has something to do with the kidnapping, there will be more information in the next Gimp Gazette.
The Gim'dom Council had emergency meeting, and decided to cast lots about the dangerous task to deliver the paint buckets to Wilber.
Congatulations mate! You're the Chosen one, you're the Color Courier! The colors are very special, the dyes are extracted from secret flowers and other plants. Once consumed, Wilber can activate infra-red vision and return using the solution path.
Oh one more thing, watch carefully where you step. The maze is full of creepy stuff. lab rat skeletons etc.
