Great atmosphere and usage of monochromatic colors, and while some of the puzzles contained within are rather easy, it's very cool to see them executed. I love the music, and I haven't yet solved the Rotating Panels and Elevator Buttons puzzles.

This is a classic mzx puzzler. The puzzles are well-designed, the implementation is good, the colors are cool, and the music is perfect. This is a must for puzzle game fans.
