Didn't get much done in the first day because I spent most of it trying to figure out a line of sight system that I ditched after a few hours of failure. Instead I've gone with this weird system where you can only see the 9 tiles around any space that you've previously been.
Since that didn't make sense as a sight system, the player is now a map maker.
If I have the time I might try to make some nicer tiles, but for now I'm just imitating the symbols used in ASCII roguelikes.
This is what I have for now!
