I played through the game before I saw what the prompt was. Needless to say: lmao.
Such good character models, and I loved how you started playing with the camera angles in the second half. It was starting to give me that late 90's Playstation vibe. Also, the hallway shot from the side when exploring the hospital kept reminding me of SNES/PSX Clock Tower.
I had a little trouble figuring out what was and wasn't interactable. The area where you input the pin, I basically found by accident when I happened to catch a sliver of it floating off to the void. I'm not sure if the camera placement to make it obtuse was intentional, but playing in the moment it felt unintentional. I'd also recommend lowering the typewriter sound. Trust, I love a good menu sound, but from my laptop speakers, it felt a bit too loud and grating. Sound mixing is a tricky art in general, though.
But who is this mysterious character at the end!? Will the good detective engage in chase? Fisticuffs? High jump challenge? I eagerly await the conclusion.
