I had this game recommended to me. There is a lot I like about this game. The music, and sounds are ethereal and really out you into the world. The voices (English subbed) were great. They really set a mood. I enjoy this style/format of a game. The storyline is interesting, and pulls you in. I read some other reviews of difficulty navigating. I had no such issues. Maybe they fixed them? I found navigating to be very intuitive and natural. Puzzles were on the easy side, but very enjoyable. They were very formulaic. There were a few puzzle formulas. (Ie matching patterns, remembering pictures, lining up things, etc) but there wasn’t a LARGE variety. I checked out the hints section and really like it. If you are stuck on any one thing, hints are locked until you solve it, so you aren’t spoiled on everything.
Overall, it took me a little over an hour to play. I don’t quite think that amount of gameplay is worth $5. I would totally pay $2, but for $5 I expect a little more challenge and more in game time. For $5 I also expect a little more variety in puzzles with some varying complexity, ie multi-step puzzles, and different styles of puzzle.
If they came out with another game, I would be interested, but I would probably wait to read a few reviews to make sure they have more content before buying.
