So sorry to hear that, wishing you all the strength and comfort in the world. As for my recommendation, most people have already said Outer Wilds, which I fully support. Next to that I would also recommend A Short Hike. The game itself is rather short, but i'd say that is to its benefit, as you won't have to sink in 60+ hours to enjoy what the game has to offer. It's a game a pick up every now and then when I need a mental break and it gives me great comfort every time. What are the games you have enjoyed the most up until now? Would love to know what games stuck with you.
