Reviews
Probably the best walking simulator I have played. It gets the vibe of the backrooms more than any other game I have ever played. Only buy if you enjoy games that are just walking through atmospheric environments.
Slow-style psychological thriller. Reminds me of movies like Beyond the Black Rainbow.
eerie

Great game
Bought this game, got stuck at the end. Watched a video and refunded the game, I can say the game visuals are amazing and the animations of the camera sway and running is awesome. But it really isn't worth 15 dollars, you only get like what? 4-5 jumpscares and its not like your actually running from something, it's just a quick cheap scare. It ISN'T worth 2 hours of walking
吓死小小的老子了 一直提心吊胆的 应该是没有追逐
Si te gustan los Backrooms o simplemente los juegos que saben crear una atmósfera única, este es un juegazo. Lo que más me ha impresionado son los gráficos, la ambientación y el sonido. Todo está tan bien hecho que consigue meterte de lleno en el juego. Hay momentos en los que solo caminar por los escenarios ya da mal rollo, y eso tiene muchísimo mérito. Además, la variedad de lugares que visitas hace que siempre tengas curiosidad por saber qué viene después. Cada zona tiene su propia personalidad y consigue mantener esa sensación constante de misterio. Como punto negativo, hay una parte casi al final del juego donde el rendimiento cae bastante y me dio un par de crasheos. Espero que lo pulan en futuras actualizaciones porque desentona un poco con el resto de la experiencia. Aun así, me ha parecido una experiencia brutal. No necesita estar llena de acción para engancharte; la exploración, la tensión y la ambientación hacen casi todo el trabajo. Muy recomendable.
very good
made me feel intrigued yet uneasy
In my opinion, this is the best game in the Backrooms universe. It captures that very atmosphere of suspense and mystery
