I'm a big fan of old SCUMM and similar adventure games (as well as text adventures before that), so was expecting to enjoy this, based on all the reviews.
Instead I was very disappointed. I thought I'd add a negative review as a counterpoint to all the positive ones.
All of the "puzzles" were in fact glorified "I spy" activities - you'd have an obvious location to click on, and would need to find a nearby object to use, which involved rolling the mouse over the (very pretty) background until the cursor changed from a pointer to a hand. Compare this to games like "The Secret Of Monkey Island" where you have to combine several objects and locations according to often intricate and twisted game logic.
I also didn't enjoy the story/plot, feeling it tried to be "grown up" without being good enough to compare to an actual novel(la). But obviously that's pretty subjective. Finally, I thought it was too short.
In summary, despite great production values, I wouldn't recommend it to fans of complex adventure games.
