Alright I caved in and bought it, beat it in one sitting. Man, what an endearing game. That Pushsquare review is on point and I agree with almost everything that's said there, including this is a recommended play despite its flaws. A sweet love letter to classic Resident Evil and Silent Hill games.
Yes, there are bugs that sometimes forces you to reboot the game. I ran into them a handful of times but loading is very quick, so didn't affect me too much. I almost fell into the same game breaking bug described in the Pushsquare article but rebooting the game fixed it. Minor, but I also got a bug where the game didn't let me get any of the trophies.
I fully expected jank, and I enjoyed the jankfest for the most part. But one of the biggest issues with the game was how certain late game enemies' attack motion doesn't seem to connect to the player character's hurtbox, but still damages me. These things can kill you with two hits, so sometimes I would end up HAS MUERTO. Oh, the game also needs an option to adjust brightness. Some places are so dark.
Enough about bugs and jank. The musical score is phenomenal, the gameplay is classic RE/SH, you can choose either tank controls with the dpad or "modern" controls with the analog stick. Some rooms and camera angles seem to have been lifted straight from RE1. The zombies don't have a lunge attack that sucks you in - you can dance your way through them with ease, which is a good thing in my book. The combat knife is amazing against basic zombie enemies - use them frequently to save up ammo! The story is surprisingly coherent and the plot makes clear sense. The actual house and the setting doesn't make sense at all but all is forgiven :)
It's a short game, with just a few boss fights (all but the final boss are gimmick fights, unfortunately), but you know what, I did have a fun time. I may revisit and even try to speed run this game. Just in terms of pure fun factor, I had a better time with this game than RE0 and post-Team Silent's SH games. This is a game I'd love to see touched up by professional dev teams (e.g., reliable performance, smoother framerates, actual cutscenes with voice acting). I'd say if the bugs get fixed, this qualifies as a hidden gem on the PS4.
