For those that don't remember, back in August, Virtual Programming updated their website to list new games they're porting. MXGP3 - Motocross was one and A Hat in Time was another. However, the developer of a A Hat in Time said they knew nothing about it and any mention of it from VP's site was removed.
Here we are in October and on SteamDB this happened, showing clearly that a something is happening in regards to a Linux version.
About the game:
A Hat in Time is a cute-as-heck 3D platformer featuring a little girl who stitches hats for wicked powers.
A little girl and her spaceship
In A Hat in Time you play as a tiny space-travelling girl with a big tophat. Her adventure is halted when all her fuel, the Time Pieces, is lost and scattered across a nearby planet. Hat Kid must now jump, fight and stitch new hats to make her way into every nook and cranny of this new world in order to restore her fuel and resume her journey. On her way, she'll bump into the menacing Mafia of Cooks, the goofy birds of Dead Bird Studio, the spooky shadows of Subcon Forest, and more!
Will be good to see it on Linux, so I will keep an eye on what happens and update you if I hear anything.
