I've decided to try this again after not playing it for a long time, and I have two questions:
Is there a way to use ascii instead of tiles in the newest version?
What abilities do the different classes get?
Edit:
Nevermind, I figured it out.
You can see the starting abilities of your class by picking up the brush near you start and then 'M'editating.
and pressing 'I' switches between tiles and ascii.
