This is one of the better freebie offerings on indiegala and a great 2002 'escape the room' style adventure. Definitely worth playing if you have the patience. I remember however with one particular puzzle in the cd and gog versions of the game, I found a bug that might still be present here. Everything had to be done in a set order, and if you missed the first step the only way around it was to use an old save game or find one online to go back and try again in order to progress (I think it involved pulling levers). Aside from that no problems, the second game is quite good too even if it doesn't quite set the same atmosphere. I haven't tried the third but judging by the critics it's probably one only for the biggest fans
