Awakening is a fair effort, and the first effort (to my knowledge) by Pete Gardner. Giving away the plot would give away the game, but let's just say it's a believable -- in the horror genre anyways -- amnesia scenario. Don't let that scare you off, though. The game has a dreary atmosphere and a few puzzles that compensate.
Also, Awakening is a short game. Most players should be able to finish in under 30 minutes; and 30 minutes feels just about right. If it was any longer, it would seem forced.
As far as mechanics go, some important details aren't clued well. Disambiguation problems crop up (especially when entering places). A rather nasty bug late in the game allows you to put the game in an unwinnable state. This area is the game's weakest.
Despite the dreary atmosphere, Awakening didn't really resonate emotionally. The areas that it paints will stay with you, but you'll remember them as you do a house tour and not as a story. The lack of NPCs may be also to blame here.
On the whole, it's a fair game for a first effort. If you've got a few minutes on a rainy day, check it out.
