[PC] [2015-20] Pursuit horror game set in wooden sewers.

Hihi! I can't seem to find any information on a game i remember watching a longplay of circa 2019, and since the last time i posted in here the answer was swiftly found, I'll try my luck!

• Platform: More than likely PC.
• Genre: Pursuit/Chase horror
• Est. time of release: 2015 to 2020. Im almost certain i saw the longplay pre-pandemic.
• Graphics/Artstyle: Realistic, Unreal Engine 5 type graphics.
• Notable gameplay mechanics: The game is first person. You start on maze-like deserted streets, which might be asian inspired, finally accessing either a metallic door or sewer entrance. You then are transported into a slightly flooded labyrinth, made up of shrine-like wooden architecture. You are then chased by a mechanical monster, which takes up the entire corridor, and has a white noh mask.
• Other details: I believe you aren't always being chased by the monster, but you're always chased by it in the end of the level (levels?). Looking for this game has been frustrating since most searches end up suggesting GOHOME, Walk or Shadow Corridor 1 and 2. I can guarantee it's neither of them haha. The longplay's thumbnail was a still of the monster head on, and i don't remember the video having any commentary.

Thank you in advance!!
