For anyone who hasn't played it yet, def. give Oxenfree a play.
It's a 2D Adventure game, I played it with my controller but I believe a m+kb setup would work fine.

"Play as Alex, a bright, rebellious teenager who brings her new stepbrother Jonas to an overnight party on an old military island. The night takes a terrifying turn when you unwittingly use a radio to awaken the island's cryptic past. How you deal with these events, your peers, and the ominous events you've unleashed is up to you."
It's not really horror, but does have some creepy and disturbing moments. They didn't detract me from the game or its story but you can relate with Alex when such scenes occur. This is a good game to play with a group or your SO, etc. since the story, characters and voice acting are fanatstic and it can really grip you. You can complete a playthrough in about 5ish hours or less.
Furthermore you can also do a New Game+ sort of thing after beating the game to check out other outcomes.
I'll replay it some time next year but for now if you want something quick to play through def. get this, it is easy to play and the interactions between characters is very well written.
