I love the mechanic where you pick a dialogue option but the character says something else instead. It took me a minute to realise that was happening though, because the game displays the option you picked first, and then shows her actual dialogue. I'd suggest just jumping straight to her words as soon as you click an option.
The protagonist's psychology was well communicated, and you're given just enough detail to know what you need to know about her past. I did end up getting stuck as soon as I left the building though, and I'm curious to see what kind of narrative starts to take shape from that point -- a process of her trying to reclaim her identity? I'd also be keen to see some more nuance from the minor characters.
