Love the game so far, you really nailed the aesthetics of the games you are taking inspiration from, the story and puzzles are very interesting, and the tension you bring to the player is very well done.
The only complain i have about the game, is the enemies or more like, how they appear thought the game, i was so paranoid about enemies appearing anywhere, through the ceiling, holes on the wall, vents, closets or even just at the end of the hallway i wasn't looking, but whenever they did appear, it was a little anti-climactic since i felt they always appear the same way and in moments were the tension made it feel encountering the monster was too casual.
Aside from that, i feel the monsters need more Sound effects or at least more unique one's, and the animations on the baton could be improved since visually it appears like William is not even trying to hit the monsters lol.
But these small flaws doesn't ruin the game at all, it's just stuff that needs to be tweaked and that's all, nothing too major, good luck on the game btw, you got something very promising here!.
