It seems that if I sit around, I heal back up to the end of the dark red bar. But it takes forever. So of course I don't wait. So am I being punished for my impatience? I think you should introduce a "wait" command where my dude can take a sit and time passes so I regain what I would get if I left the game idle.
It would probably be good practice to introduce a frame limiter so you don't fry graphics cards, I don't need 1000 fps.
I dunno, this game is too hard for me. I can't beat the two dudes in a room in the tutorial. I guess I just suck
