The game was genuinely great, and I would have definitely given it a 4-5 if not for the part where you sneak past the old lady. I'm not sure if my game just bugged, but if this is the intended experience, it isn't a good one, and retroactively brought the whole thing down for me. She just straight out sees me through the walls and when I try to stay put, she stays put, and turns in the exact direction that I try to move. I would highly recommend just putting her on a static path with clear indications of when to pass and when not to. This is the kind of situation where there is no such thing as "too easy," you had the right idea to not have combat sections, now you just need to also do something about this unnecessarily difficult forced stealth section, and this would be excellent.
