What's your "sleeper hit" recommendation to the community?

Khazan is definitely the title I think of. I was very sceptical about the game and its aesthetics mostly founded by impatience during the demo. I gave the demo another shot, ended up liking the game quite a bit, and now I'm finishing up my first playthrough at around 50h. I feel like it's a game that has gotten quite a bit of attention from "hardcore" soulslike fans but hasn't really entered the mainstream yet - it very well could, tho, from a quality standpoint. The combat is quite unlike any other soulslike, and the shade cell look is a good change compared to most semi-realistic looking soulslikes I've played before. My only gripe is the rather cliché and empty story - they could have done so much more - and the level design.

Have you played any soulslikes recently, which you would classify as a "sleeper hit", which more people should be playing?
