I really enjoy the aesthetics and music. I felt claustrophobic and being stuck in a small space with the enemy made it even more nerve-wracking; plus, the fitting music made me want to escape but I know there's no escape and the only path forward to kill the enemy. It's exceptionally immersive.
I agree that the controls do feel experimental and I have no clue what I'm doing lol except trying to run away from the hostile knight.
It's a great entry and probably one of the few games I've played that delving into the abyss feel like one.
