Looking over what actually came out this year, my GOTY is easily OMORI. With all it's kickstarter woes and being an RPGmaker game aside, Omori closes it's first act with a gut punch and continues to kick you while you are down for the rest of it's 25 hour play time.
Other games I played that I either haven't finished or didn't think measured up:
Cult of the Lamb: I liked the game, it just didn't have as much depth as I had hoped. Once you learned brainwash 90% of your problems go away. Had it been $15 I could recommend, but not at $25. Maybe with the content update, but I'm not holding my breath.
Tunic: Very cute Zelda clone that I need to get back to. Worth playing on Game Pass
Signalis: An okay survival horror game that tries too hard with the spoopy metaplot instead of actual horror.
Vampire Survivors: A fun time waster letting you kill a half hour at a time and still feel like you are making some sort of progress.
