Really great artwork! I like how inside the houses there is minimal colour but enough to set the atmosphere. Also liked the details like seeing the snow fall through the windows, have the snow stop in time and how the snow moves when you fly.
Two things I'd comment are that the game is a bit too easy (i had the feeling i could always just go in, drop presents and leave without needing Santa time) and too long (maybe the eighth hours out game duration could be shorter). Otherwise, really liked it!
