Nothing better than summoning St. Nick on Christmas Eve :)
I enjoyed the perspective change - as soon as Gunter tells you to wake up you know you're not in a normal environment. I would have liked to discover more about the household and my fellow 'tenants' but it just added to the odd, curious ambiguity of the game.
The art style in particular reminded me of games of your like X111 - the shading/texture gave the whole ambience a dark, otherworldly vibe.
Merry Christmas!
