The good news is that there is no limit to the number of moves you can make, although there is time limit on each level. The bad news is that with virtually unlimited number of possible combinations of mirror positions, the game is very difficult even on the first few levels. Higher levels put many more complex obstacles in your way, such as a lamp that must be triggered on, "polarisators," random reflecting prism, locks, and many more unique objects. This makes Mindbender a very challenging game that newcomers to puzzle genre should avoid, unless they are prepared for some very frustrating sessions. Recommended, but be warned of its high difficulty level.
Note: Use A and S keys to rotate mirrors, and arrow keys to move the cursor.
