GOG's Winter Sale is well underway, bringing with it loads of deals and mystery games. Last week, Double Fine's Grim Fandango Remastered went free-of-charge—and while that particular offer has expired, Night School Studio's wonderful narrative adventure Oxenfree is now subject to the same complementary treatment. 

Which is great news because Oxenfree is really good. Besides telling an interesting story about supernatural mystery, relationships and growing up, the game's dialogue system is the one of the most intelligent I've ever come across, where conversations flow almost seamlessly into the next, and whereby NPCs react to silence and/or being interrupted.
