It's good, but not the best.
The puzzles are few and they aren't too difficult. The only one you might have trouble with is a board game and a snowmobile, but most of them are easy. There are chores in this game. Mindless chores like making a bed or cooking breakfast. Not exactly fun. After the first half of the game, I actually stopped doing the chores and I didn't get in trouble, so I question if the player actually has to do them or just say they did.
You are able to go outside and walk around in the snow. I thought that was fun since the graphics were really good and did a wonderful job of creating a beautiful winter wonderland.
The mystery was pretty good. The first part of the story is vague and just plain strange. After you get past the first half, the story starts to pick up and move faster. There are also a lot of convincing red herrings. I had no clue who the villian was until the very end.
The game in general was pretty good, but it didn't have all the substance you usually find in nancy drew games.
