it was pretty good! the best moments were when something unexpected would happen and i'd have to deal with a new situation on the fly while already managing my spacing and ammo, like an enemy getting stuck behind a barrel in a corridor and us having a tense walk back as i try to get him in my sights, or a strong enemy using a weaker one as a shield to approach me. i also really liked the accuracy mechanic
aside from annoying spiders jumping out of the darkness and hitting me before i got a chance to react, the weakest part would probably be that because of the procedural generation there were no set pieces (outside of new weapons appearing) to change up monotonous gameplay or create interesting gimmicks like there would be in a normal horror game
