I had a good time playing through this one with a friend back when it came out. It's got a very cool time-travel mechanic that sets up some pretty interesting puzzles. There's also some good humor in the game, but I found it got a little cheesy at times. The game does also suffer from the age-old adventure game problem of having some rather illogical and annoying puzzles in a few places.
Overall, it's a good game but I didn't enjoy it quite as much as the first game in the series. I will admit that there are a few bad design decisions in the first game but for the most part I liked the plot and puzzles in the first one better than this. But this will still be a good time for any fans of adventure games, especially at the GOG price. Definitely recommended.
