So much for "taking it slow". I just beat it. Gameplay-wise I think the game isn't very satisfying at all. The puzzles aren't that interesting, the solutions are too simplistic. There's really no possibility of getting anything wrong. Pretty much the only thing the game had going for it in the end was the "experience". The story was neat I guess, but even that is really short.
I feel the game is something which would be more worthwhile if it's part of a collection, but isn't really that substantial on its own. 8 bucks isn't really value for money for the experience at all, especially when the same amount of money can get you lots of other stuff on the eShop or any other store with much more value and gameplay. This is a 2 hour one-off experience which has zero replay value, really basic gameplay, and an interesting use of audio-visuals to project a simplistic "alone on an abandoned spaceship" experience.
