Friendly units turn green when you target them. You can see Nahla trying to heal Sir Camil in the first screenshot. In the second Sir Camil is improving his own defenses.

What's next?

• Rewrite the action selected tile to show what an action will do once it's selected. I'm halfway through it now.
• Update the tutorial. It's currently a huge wall of text - maybe I can spread it out throughout the mission.
