The appearance of the game is rather simple, but this clearly. There's a lot of fun to agonize the brain, such as the laser beams and mirrors and prisms must be aligned and combined to achieve the goal. For a fast lap in between so not very suitable, because you have to experiment a bit in the later levels, until it fits. But the game saves when you exit the current interim status and man kan make later there on. Funny it is to look at and be amazed about what totally different solutions they have found the solutions of other players online.
