Tunic is the big one that I want to go back to, it was very intriguing on its face but some of the design choices were off-putting. I actually finished most of the games I started this year, surprisingly enough. Any of the other big games I can think of that I didn't finish were just because they are on the longer side, but I am still actively playing them (see: Soul Hackers 2, Xenoblade Chronicles 3).
I finished Stray as part of my "let's finish some 2022 games" stuff but it took me 3 separate "periods" of picking away at it, which is a lot for a 5 hour game, and while its extremely pretty and atmospheric it's also not at all a cat simulator and has middling gameplay. I'm kind of glad I played it because I did enjoy seeing all the set pieces and a few of the puzzles but I think it was very overrated. Not a bad game but pretty average.
This was basically the exact same experience I had with Stray. I started playing it when it came out since I already had the PS+ plus that let me play it for free, and I didn't finish it until a few months later. It really shouldn't have taken me multiple sittings months apart to finish such a short game, but it just didn't grab me that hard. As you said, it was worth seeing in the end I think, mainly for the lighting and environment/character design, which I thought was quite good. But I think the "oh you play as a cat" gimmick really pushed it into getting way more talked up and overrated.
