This is a good list! I'll be checking some of these out for sure. I also have some overlooked games of my own I'd like to list. No links since I'm on mobile, but I may edit them in later.
Qbqbqb (30): Simple arcade game with nice animation and catchy music.
Goetia (496): Spooky point-and-click with some very good puzzles in my opinion.
Under Leaves (530): Relaxing hidden object game with a nice art style. Great game to play when you're stressed and want to turn your brain off.
Year Walk (1197): Horror adventure game with an off-putting atmosphere and interesting art style.
The Last Door (1541): Horror point-and-click adventure game with a lovecraftian feel.
I'm glad you decided to give it another shot! It's one of my favorite adventure games and I never see anyone discussing it.
