I'm a bit lost as to what to say about this. Surely, some people might enjoy this interactive museum, but I cannot help but feel like it could never ever be wirth 20 bucks. My recommendation could have been different had the price been as well.
To make it clear - this is a story that can certainly resonate with certain people, however the price makes it not worth too try and find out whether you are one of those people or not.
This is a poor man's Penumbra; the game has 2 primary ways of conveying the plot (for what it's worth - more on that later) - audial diaries and various letters spread about in the house. A diary entry plays in the background each time the player finds the next plot clue, and is then added to the player's library/journal, from where they can play the recording again or read the transcript. Other than that, the house is full of various letters and cards, which can be read if so desired. The content will provide for 2 hours of play time, if explored fully.
The aforementioned house is, by the way, the only location in this game. It's not very large, but has enough dark corners to make the player revisit some rooms; mostly, however, all the clues are pretty straightforward and won't require any particular pixel-hunting.
The environments not very interactive, as the most a player can do is move several small objects (which represent no plot value most of the time) around. With the exclusion of a few exceptions, all interactivity boils down to opening doors, reading letters sticked on surfaces, and turning the lights on. The amount of objects that had any relevant information on them that required examining in 3D can be counted in single digits; for the record - there is an option in this game to rotate some objects in all 3 axis.
The plot mainly consists of one main storyline about a girl (main character's sister). There is also a branch going into the stories of the rest of the family - the writer father, the mother and her colleague ♥♥♥♥, and finally her mysterious brother the pharmacist. There is not much to be gathered all in all, but these branches do provide for a nice distraction from an otherwise monotonous story.
It is hard to comment on the main story itself without going into spoilers (there are not much to be made however). It cannot brag with clever twists or an ability to create a strong emotional bond, even though there were a few unexpected moments. The ending is particularly dissatisfying - it does not solve any problems raised during the game and just reaches an easy deus-ex-machina conclusion, if such strong terms can even be applied in such case.
Speaking of the social commentary side of the plot, there is not much to be either. There is only 1, perhaps two moments where some societal problems are pointed out. That is fair enough - but no further commentary has been made on these topics. Even the reaction of the characters isn't described with more than 2 paragraphs of text.
The graphics are relatively stylised, yet it can still be often seen how poor they are. This game is in many ways comparable to Dear Esther, and the latter has done a much better job at visuals.
It's also worth noting that the game is quite glitchy. I got stck at one point because, despite having a key to the next stage, so to say, I wasn't able to open an appropriate door. I tried restarting the game, only to see the "New Game" button - my save file didn't like my hard drive, apparently. Having turned to the forums, this seemed to have been a pretty widespread issue.
Furthermore, objects sometimes would glitch when picked up, and not be displayed.
Gladly in Gone Home it is easy to reach a previously achieved point in the plot, so even after losing my save file I wasn't set back too far.
All in all, I must say that even thuogh I wasn't bored to the point of quitting the game halfway in, yet that is only due to my having nothing to do at the time. Your time is much better spent playing other games, including indie ones - it is very easy to find a better way to spend your time. If you are interested in such an interactive museum type of game, I suggest you try Dear Esther, which had managed the implementation of it much better. Finally, there is always Bastion with its narration - though that would require more actual gameplay.
