THANK YOU, you hit exactly on my problem with the game: it's such a jankily-built game for something the devs seemingly are hinging their company's future on and spent two years building.
The actual GAME part of the game feels like it's about to break at every moment. Clicking on interactable objects is a chore. The inventory system is so obtuse you keep encountering minigames that clearly were intended to play differently but you have to do an awkward two-items-at-a-time dance because of inventory size.
I support the development of transgressive art projects, but for all the marketing around HORSES this ends up being a story that REALLY hopes you haven't watched much giallo from the 70s, 'cus this is just a bunch of giallo trends stapled together. What's worse: the plot doesn't really commit to saying much about the horses themselves beyond vague inferences. In a way, it's authentic giallo in that its plot is kneecapped by what feels like cut content or a writer forgetting to close a loop.
It could be an excellent novel, animated video, or straight up live action short film. But instead it's a video game. A video game that does not really demonstrate any evidence that my choices matter. I have no impulse to replay sections and make different choices because there's nothing (either in-universe or meta-textually in the game's menus) indicating the choices impact anything other than dialog.
