All Alone

This really is a 'mood piece', and should be played as one. Don't expect very much interactivity, or that the choices you do will have much effect on the final outcome (this is, after all, a horror story). The writing is generally good, and manages to convey an increasingly creepy atmosphere, though the parser is only adequate, with a bit too many unknown words. Many people find the ending a bit confusing, but it's not bad, really. All in all, this is a good, if somewhat flawed, mood piece. With a better parser and a better ending, it would have gained an extra star from me.

Note that the author suggests (or rather requires!) that the game be played at night, in a quiet room, and with the lights off. I agree, and also recommend you use an interpreter that supports sound (and no, there won't be any loud screams to scare you, just a few well-placed minor sound effects). The result should be an increasingly uncomfortable experience as the game progresses, which for this type of game is good thing!
