I have mixed feelings about this game.
On one hand, the puzzles are nice and not obvious (at least for me), the voice acting is great and the music creates a nice ambience.
On the other hand, there are just two puzzles. It took me a long time to realize what the clues for them were, but once you solve them, this becomes a game of pushing buttons. And the buttons are... annoying. They were particularly annoying to me, because I didn't manage to solve the puzzles until my third run of the game, which meant I had to play through the intro three times, as it seems to be non-skippable and there is no save feature. And the intro and the starting area have a lot of buttons. What makes it even more annoying is that most of the buttons make absolutely no in-game sense, since they are on one cable within an arm's reach of each other.
It certainly seems that for a world this size there could be more puzzles (one per memory piece or so), including something exploration-based, and less buttons.
