If you enjoy snowmen, crafting, and puzzles, then Owlet's Feel the Snow may be the game for you. The first title from this two-man development team hit Steam Early Access last Friday and is on sale for 20% off until this Friday.
The core conceit of the title is survival. You'll go out in the world, battle foes, gather materials, and craft shelter/gear/food. The more you're able to build up your resources and home base, the further afield you'll be able to go. There are classes - Melee, Range, and Mage - from which you can choose and (to a limited degree) spec out, and all of this can be done cooperatively with up to three other players.
Feel the Snow is available now via Steam Early Access for $8.99 (regularly), and just $7.19 (the sale price) until this Friday, October 21. The title supports four player online co-op throughout the main game mode.
