Reading the other reviews here I got a bit nerveous about having ordered the game. Some of them speak of problems getting the game to run, while others sound almost like they were made by the developer to promote it.Luckily when I got the game it ran just fine. No crashes yet, having played around 80 of the levels.It's a nice, slower paced game to relax with after some hours of action games. Some of the puzzles can be a bit tricky but that just makes it more satisfying to finally solve them.Summing up my impressions: Game works fine on my year old PC running WinXP Home. It's a different kind of game from most I play (RPGMMO, shooters and strategy). It's fun to play around with all the gadgets and tools. Might have limited replay value once you find the best (simplest) solution for the puzzles. But the 200+ levels will last a while and then you can make your own levels and have others try figuring them out.
