All my free time lately has been going to playing Hollow Knight.
If you like Metroidvania type exploration and combat system, and a Dark Souls saving and death system and the similarly hidden lore, this is probably a game you will very much enjoy. It also helps that it's easily the prettiest 2D game I've seen in a long while. I like it even more than Ori and the Blind Forest's art (the quality is equal, but the style and atmosphere suit my tastes more).
Edit: Also, if you're a person like me who dislikes levelling systems - congratulations, this game doesn't have any. You get more powerful through equipping different types of equipment, upgrading your main weapons and spells, and getting better at playing. Screwing yourself over by picking wrong stats is not possible, and you can change builds whenever you like. Also brief warning: movement speed is an upgrade. To some the game might feel painfully slow at the start. It picks up relatively quickly, though (by the second area you get an upgrade that speeds things up).
Also the last free DLC for it just came out, so it's a good time to get it~
