Well... bought, played and beat Among The Sleep (I love those quirky little games... don't judge me!) aside from the fact that it's DAMN not worth 20 bucks - mainly due to the length of it - (10 ... maybe ... I bought it for 17.99)
I would say get it ... if you like those type of games (it's a mix of horror kinda... and just a story game ... mainly just walkthrough and do little puzzles... although it does have some 'avoid this scary *** ***' parts)
A friend of mine said the exact same thing. Sounds like Gone Home. Short, but a very story-driven experience. While that not exactly a bad thing, the pricetag doesnt quite justify it.
Transistor was almost close to that point, but I loved it xD
