Cute game. I like it even though I am a girl. Hope for a "girl version" and lesbian opportunities.
Have found a bug: Bought a white cat. After entering a name, i get the error: "Error: the passage "My" does not exist".
Also, after missing the notice about visiting the orphanage, I chose the "go back to orphanage" option (and being "rewarded" by Eva) and could not find a way to get to King's Cross station to board the Hogwarts express - nor any other way to get to Hogwarts.
Maybe make the "emancipation letter" an inventory item, then it could be turned in when the player is ready.
