This game does contain low poly count gore and gunshot sequences.
"Sensory horror" is a good way of putting it. There's no jumpscares, but rather the general feeling of uneasiness. I really enjoyed the vignette storytelling; it adds to the feeling of dread and confusion that adds to that sensory horror. It gives a "Neverending Nightmares" experience through a 1990s aesthetic.
Got it on sale in the Switch shop and used my Nintendo eShop coins (so I got it for free). It took me less than an hour to complete, which is understandable because it was made by three people, basically. I really enjoyed it, and I also wish that I could experience more aspects of the story. Perhaps, though, the game's charm is in its brevity and the big question marks at the end.
