The title says it all really. According to the manufacturers 'on a particular release' there are certain faults. Unfortunately these faults cause the game not only to freeze but also stop you being able to proceed at all. I was told that the solution to one of these was to start again right from the beginning with the background music set to zero. Bit of a con when you can't use the music and have to start from the beginning several times. After 3 of these faults I returned the game.
If it could have been played right through it was a fair adventure game, the voice overs were throughout the game, novel for the ds, but very irritating as he comments whenever you click on something. The story was OK but some of the puzzles were nonsensical. Apparently they made more sense in the original on the PC but the detail just wasn't there on the ds.
