Thank you, and thank you everyone else who has commented below! Glad you all had a good time!
There are some posts on tumblr discussing the heritage features, if you are interested: for example this one mentions it briefly, this second one, and this third one. I think two are before the demo was updated :D
I will probably come back to it later to try again make it so that taking multiple options would be possible. The posts talk about some of the issues regarding this. It was a lot of work for C2, and I don't immediately want to mess with it :D
