Hey, thanks for playing.
The auto healing is meant to be a reward for players who play well enough to not get hit often, so you're right about not waiting. Unfortunately the thing that's supposed to balance that isn't actually in the game yet (dangerous enemies appearing at night, adding a timed incentive to exploration and the like.)
My bad, that was more of a debug thing for me. The game is limited to 60 fps, but the fps shown there is an extrapolation to show how fast your computer is rendering the frames. It's helped me figure out where optimizations need to be made.
Apologies, I probably should have made them easier. The only reason there's two is to make the lock on required.
