Fragments of Him is essentially a visual novel. You interact with items in various small environments and hear narration from several characters. It's a 2-3 hour experience. A pretty good, touching story and the most mature treatment of sexuality I've seen in a videogame thus far.
Among the Sleep is a first-person exploration game with a bit of puzzle solving. If you're looking for a truly scary experience, this isn't it, but the subject matter does get a bit dark in the latter half. It's basically first-person exploration with a bit of puzzle solving and from a unique perspective. It's an approximately 3-4 hour experience. The performance was quite bad, with frequent hitches that somewhat ruin the mood. I didn't find it to be worth the asking price, personally.
