A bit late to the party, but I finally got in the appropriate retro mood and finished it. Glad I got the 'promise' ending - don't know how others play out, but this one felt perfect considering what happens in the story.
I'm usually a bit snarky when it comes to purely allegorical stories, but this one packs a punch, I think. Cryptic and I am not going to pretend I understood it the way the developers intended it, but it is one of the fascinating video game stories last year. Very art house, very personal. It's like early Fritz Lang, Kubrick, Lynch, Haneke and a few Japanese artists got together, travelled in time to GDR, then to late 90's and made a game about love, connection and cancer. I can see it working as a comic or a novel maybe, but it is purely a videogame story and that's refreshing when most creators want to emulate film.
I liked all the gameplay "limitations" like limited ammo as well as limited inventory space and puzzles were fun - not particularly hard but always intuitive. Good stuff, definitely in my top 20 of 2022.
