Atmospheric, entertaining game with a high re-play value. I recommend playing both versions just to experience the different endings (I prefer the original release.) The puzzles are simple, but not too easy. Despite some repetitve commands and a linear plot there is still some legroom in Snowquest's simple yet picturesque landscape. (Other games fall short in this regard, such as also-ran Condemned and the notorious Photopia.)
The first release is less artful in its use of language, less subtle in its metaphor (which is saying a lot!). However, the revised ending (Spoiler - click to show)involving time travel is less realistic in the context of the game world. The beginning of the game has the almost magical mood of a fantasy; the original ending balances this out with a down-to-earth scenario that is equally believable.
Critics are howling about the (Spoiler - click to show)three "realities" in this game. I did not find this confusing, but rather I thought it was implemented nicely! My straightforward interpretation is (Spoiler - click to show)the first and last realities are parallel. The middle scenario (apprentice finds the pilot) is an alternate reality for either the first or the last reality. The author made this clear and the subtlety adds to the game.
