About Hyakki Yako: OH&S

YOU WANDER FOREVER IN UNDEATH

Hyakki Yako: Operational Health and Safety is a first-person horror game. You play as Haramita Renkai, salary-man by day, exorcist by night. Renkai is trapped somewhere deep in the underworld after a ritual gone awry. Armed with naught but his wits, his talismans and a burning desire for self-criticism, Renkai attempts to flee the grasp of the ravenous Demon Parade and escape back to the mortal plane.

[h1] Run around the endless maze of back alleys in search for talismans. You can cast them to banish red evil fog coming your way but keep in mind you have to collect 6 of them... Banishing take some time and is not very effective so you will probably fail in the process. You will die a lot and game will repeat itself with a bit changed wall and floor decorations. To be honest not worth the hassle. [/h1]

A wonderfully eerie, surreal, and delightfully chaotic first-person horror game that breathes fresh new life into classic, dream-like walking simulators! Stepping into the heavy boots of a daytime salaryman and nighttime exorcist trapped deep within a shifting underworld labyrinth is every bit as exhilarating and tense as it sounds.The low-fi visual design and the claustrophobic, meat-walled alleyway layouts capture that magical, high-energy arcade nightmare vibe flawlessly. Balancing tense real-time exploration with hunting down 6 elusive talismans to banish the encroaching red evil fog creates an incredibly frantic and rewarding gameplay loop. Navigating the scaling speed of the relentless Demon Parade while managing your unforgiving stamina meter keeps your evasion reflexes working at absolute maximum capacity.It is the absolute perfect, light-hearted yet moody single-player gem for testing your puzzle-survival reflexes, laughing at mocking death messages, and enjoying a uniquely focused artistic ride—all for the grand price of absolutely free! A brilliant, tightly contained indie oddity that is a must-play for any fan of experimental retro horror. Definitely recommended!

Absolutely lovely game, deserves more attention. I will say I started cursing out the demons instead of being scared, though lmao

It's too annoying and stressful. The reason why I'm saying this is because the map makes the game hard for you and easy for the monster to catch you. The monster gets faster the farther you are from it, and it noclips through the damn flesh walls whenever you try to run after getting 6 talismans, even the stamina before that really sucks. Wait until you play Baldi's Basics, which sucks and needs adjustments just as much as this game and Death Forest Abyss (which is a ripped-off and fanmade version of the original game by KAZZ, which I wish was Steam). By the way, go play the original Death Forest, in that regard, or not if that game is just as stressful as the other games I mentioned before. I'll give this game a negative review. Don't forget: The sounds are really damn annoying. I don't understand why games in this decade are for the "Pro-Players" only and are blender-made trash and content meant to lure you and rip you off. No offense to the developers of this game.

I haven't finished it. I plan to and some of my playtime is me getting distracted but so far i am enjoying it! id recommend it happily. my only complaint is i wish we could run for longer to create distance but that's ok, i like the changes with each death and it is frustratingly enjoyable? its hard to explain but again i would definitely recommend it to anyone who wants to try a fun free game!
