It's a very nice game. We played it from the CD version, and the graphics were also great (but certainly not as much as on the DVD). The sound is great. Two characters are a great idea. Some puzzles can be solved only by their cooperation (!!). But these two characters never meet in the game. We've solved all the puzzles except the last. It is very difficult and it has only a slight lead (but it has :-) ). We had to use the solution guide (it's "setting a few rows of buttons on one machine") ... I highly recommend this game - but the player's patience is needed :-). And in one case - also good hearing :-)).
