I've been playing a ton of Spiritfarer on Switch and after 20 hours or so with it I can confidently say it's a very strong front-runner for my GotY2020. Besides being one of the most warm and heartfelt games I've ever played I love the hand-drawn art direction. I even went and bought the rest of Thunder Lotus' catalog since they were on sale and they also have that same amazing hand-drawn style.
And the more I think about it I gotta say my favorite technological advancement in modern gaming is that games can now look and move like crisp and clear hand-drawn animation; something that I've always wanted since I was a kid.
So, as of right now I'll give Spiritfarer my pick. I love the Ghibli-style softness to everything and how perfectly the animation expresses such subtle emotions (those hugs, man!). And the character designs are among the best I've seen in my 40 years of gaming!
What are your favorite hand-drawn games? The inevitable Cuphead (I love the art direction, butt fuck do I hate playing the game)? Something from SuperGiant? Darkest Dungeon?
