So I'm playing through this and I'm enjoying it so far, but there's a few small niggles that pull me out of my immersion. This game is set in Britain, but you're using the american spellings for everything. We don't refer to our mothers as "mom", we call them "mum", and we don't say math we say maths. There's probably going to be a few more things later on in the same vein, but I've not got to them yet.
As a bit of constructive criticism, if you're writing a game set in a country other than your own it would help to know the differences in how things are said and done so that it's true to what you're trying to do.
