I tried out the demo, I am not too sure what I am doing in the nog game and the music in the fireplace option is kinda dissonant, wasn't sure what song I was hearing.
Very cool idea though!
Thanks for trying out the demo. The music has a bit of Christmas Eve /Sarajevo by the Trans Siberian Orchestra but it is very watered down version. The plan is to have different music play for just the fireplace section. For the nog game, you can drink eggnog (or not) and crank slowly for some encounters. You have to either make it to midnight (the time is in the lower left hand corner) or crank to the maximum to see the endings. The entire game is a work in progress for later this year.
