Excellent game except for the color of the background. You can't see the switches! Fix that and I can definitely rate this 5/5.

I love this game. it makes you think.

What could possibly be better than loops of zen with trains?!

A very clever game with more depth than meets the eye initially. The "desert" background gets annoying quickly though as you can't see a thing!

never mind! i got it!
