Eh, this was alright. It seems like you were going for an exploration-based story told visually. The 3 hallways in the beginning that look somewhat similar but have clear differences is nice--I really like that, though it is a bit tedious using the arrow keys.
But the story really falls apart because (1) it quickly turns into a fetch quest with exposition dumps, and (2) I don't know this story or its characters very well, and the game didn't do much to tell me about them. The goal is unclear from the start, and I have no idea who this character is, what she wants, etc. This makes the story fall entirely flat, and the final choice especially is meaningless to me as a player--does this girl want a normal life or to find her brother that we don't know about? I have no clue, and you certainly didn't tell me, so, frankly, I have no investment in the choice at all.
Overall, it's ok. Some good visual storytelling, but the writing definitely could use some work.
