Snowquest is a competent work with a little extra depth than your usual short game. The first half of the game has a great sense of setting; the first scenes especially have a sense of peril to them. It uses the (Spoiler - click to show)"it was only a dream" trope a number of times, but uses the dreamlike atmosphere in a way that keeps the scenario interesting, rather than feeling like a cop-out. I especially liked (Spoiler - click to show)the scene where you discover yourself in the downed plane.
The game changes dramatically during the second half. While the elements of the first half don't match up to the second half's parts one-to-one, I still enjoyed the dream logic going on, even though the ending was forgettable.
An enjoyable way to spend your night. Not a perfect work (others have noted problems with implementation), but better than most reruns.
