For fans of point and click adventures with a twist, you may want to take a look over at Last Christmas that recently added a Native Linux version. The game released on Steam in April, with the Linux version arriving May 17th.
Since it appears to be on the short side, the developer hasn't really explained all that much about it. Noting that "Last Christmas is a short and not so sweet point and click adventure game. Join Frankie up in the mountains at the family cabin and help him to prepare the perfect Christmas for his girlfriend Betty, but watch out, things aren't always as they seem..." and a very brief promo trailer is below:
The game has 4 different endings, some dark humour and 24 achievements to hunt down. With a few point and click modern touches like double click to exit scenes and a hotspot finder.
You can find Last Christmas on Steam.
The next game in the series is First Christmas, which also plans to have a Linux version and it launches later this year.
