The list is quite extensive, so it would be great if y'all could point out some of your personal standouts here
You simply need to try A Short Hike. I do believe it is a sin to not play it. This is one of those experiences I'll never forget.
I also really liked Jam and the Mystery of the Mysteriously Spooky Mansion (jeez, what a name...). It's a charming whodunnit, where you already know who did it.
You should also try Minit. This is the sort of game that I aspire to make myself, top quality stuff. There's a huge world with secrets and puzzles to solve, all oozing with charm.
Oxenfree, along with A short Hike above mentioned (what this amazing little game has managed to achieve is worth of every praise and beyond), is one my favorite games ever.
Hidden Folks and Kids are two minimalistic gems.
Democratic Socialism Simulator and Clam Man are very fun and enjoyable.
The white Door is the right amount of unsettling and a very well written puzzle game (you can't expect anything less from the Rusty Lake team).
I'm currently playing one of the other "bigger" games in the bundle, Night in the Woods, and liking it so far. Celeste is also a big title and a classic worth the praise, but be ready to some incredibly difficult challenges (given you like the genre).
Looking forward to try Stardrop and 2064: Read Only Memories.
