It should be easier to let me just start with space or mouse click, pressing enter makes me move my right hand to a different pose and then move it back because that's how you shoot.
The restart with R is cool, but I'd rather have it in a different key, I pressed it by accident like 4 times, including the last one when I decided to drop off. Maybe on dead you can restart with space-enter-click again?
Restart after you held R for few seconds? or after you clicked manually a refresh icon button.. I don't know.
Other than that, the auto aim weird mechanic is nice (or maybe I didn-t figure how to aim)
Keep doing a great job!
