room18: Yuki no Hi no Heya (room18 雪の日の部屋, Room 18: The Snowy Day Room) is the eighteenth game in indie developer Ichima's Escape Room game series. It's Christmas yet again and this time, you are trapped in a fancier Christmas-themed lounge instead of a cabin in the middle of nowhere. There appears to be some more personally involved puzzles compared to last time, as if someone is watching you.
Spikestuff in this run knows exactly what to do and escapes from the house with ease, hoping there's someone in the nearby town to celebrate the holidays with this time.
