This game was pretty perfect until the killer really showed up. I almost had a run-in with him before you need to and the way that he sometimes walks and sometimes run while patrolling is really unnerving, much more so than the snipping sounds because it makes you think he might have spotted you.
So the stealth is good but the chases are not for a few reasons.
1: You can take one hit, a second one kills you, but it felt like at least nine out of ten times he'll attack you twice in rapid succession so it might as well have been one.
2: The killer is too fast, I know Puppet Combo inspired this game and he usually does this too (but didn't in his best game, Murder House,) but it feels neither like 80s slasher villains who almost always just walks toward their victim or sneaks up on them, nor is it all that fun when like I said, you almost always get one-shotted. I actually think the only place where I was able to lose him was in the stairwell, making all the hiding spots useless, especially since just hiding around corners worked fine for the stealth.
I'd have made him slower and just removed the health system entirely since adding more health would instead make the Snipper seem weak. Alternately, make him loose your trail quicker since there's no way to actually make much distance between the two of you.
I liked the vhs static when you were close to the killer, it made for good situational awareness. The chromatic aberration really didn't feel like it was from a vhs though, felt quite digital.
The map stayed saved after you did something, so if you open a door, get killed and sent back to a checkpoint, the door will still be open after that, and quite frankly that's also the only way I could see myself getting past the killer in the scissor corridor as he is now but that shouldn't have to be the case.
I first tried it with an Xbox 360 controller but it only worked with the analog stick, not with the D-pad so I noped out on that, the keyboard controls were all good.
But yeah, if you nerf the killer and instead make the penalty of dying a bit harsher I think it would improve the game a ton. The atmosphere and stealth stuff is already really good.
