Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.14/day in the week to Jul 30 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Le jeu a été sympa à faire, ayant peu de temps à faire de longues sessions cela a été un plaisir à faire, ça m'a fait sursauter par moment, même si on a la conscience tranquille. Hâte de voir le prochain.
Great Game! Had a little tough time playing it. Got stuck near the end but still love it. See my gameplay below! Thank You Hollow Signal Games. Looking forward to playing your next banger! https://youtu.be/IMHeZapaIsc?si=GO0XGw5KCioayWER
Un premier petit jeu d'horreur indé qui vaut le détour ! Un couloir de 45 min qui fait du bien / qui fait peur ! Très bonne ambiance je vous le recommande

Very Much enjoyed this game. I get that its a jump scare horror but for me i read the notes and learned about what happened in the abandoned hospital. Love the plot twist, especially since I had a good idea of the larger story. I think the lore is fun to find and the game boasts a solid sense of tension.
Je recommande clairement ce jeu. Une ambiance pesante et efficace, avec de vrais moments de tension. Impressionnant pour un premier jeu indépendant. Hâte de voir les prochains projets du développeur.
Very cheap jumpscares in the first minute. I would have been okay with how cheap the game is made if it tried to draw you in instead of be mediocre.
vraiment top !!! rien d autre a dire ! Merci a vous .
Absolutely loved it. Thank you Rudy for this awesome experience. I can't wait to see what you and your team are cooking up in the future!
Pretty short. For the dev's first game I thought it was a solid effort. I enjoyed it. The music was good. Remined me of F.E.A.R. Story was decent. More jumpscares than horror but the atmosphere is there to make up for it. Good amount of exploration. Like I said. Solid effort. Be interesting to see if they make another game.
