Thanks for the comment! :D
I was really happy with the chalk boards, they were meant to be a tutorial only thing, but the more advanced levels just looked bare without them so I added them in. lol.
From play testing we decided the minimap always showing your location was important for people who didn't know the maps layout, so they always knew where they were. Maybe though I can make it so a room that had both you and a guard in it showed up as a split of both colors.
Something to play with when the voting is done I guess.
