Copying my previous comment and also adding some more games to it:
I liked:
Viewfinder – a puzzler reminding me of superliminal
Let's! Revolution – an interesting mix of minesweeper and a rougelite
Sea of Stars – an RPG, with turn-based combat but with traversal similar to CrossCode. Not much of the story is revealed in the demo, but the characters were interesting
The Cosmic Wheel Sisterhood – "a narrative experience" (somewhat of a VN with more interactivity) where choices matter. Hard to judge how good it will be based on the demo, but I liked the vibe.
And an honorable mention to a demo that was already available last time:
It's been released two months ago, it would be really weird to put it on such a deep discount so soon.
