Thanks for the review flotsam and Jenny. I have not personally played the game yet, but I've watched a full let's play on YouTube. The player was very entertaining, and I think he liked the story overall for the most part (with the exception of the ending), though he did not enjoy the game as a whole.
Maybe it's because I was only watching and not struggling with the controls myself, but I enjoyed the game well enough. It was not nearly on the level of the first two games. I liken it to Lost Horizon 2 in many ways - not on par with its predecessor(s) but an okay experience. I do intend to get it and play it myself eventually, but not until the price comes down considerably, by which time I will have forgotten most of the puzzle solutions anyway.
I find it overpriced for what it is, but I do appreciate that some effort has been made to fix the controls.
