Lol, and to think I just purchased PFE a few days ago. Seriously though, this is great! I'm basing my current project on PFE, but this will definitely help with getting a grasp on more "vs fighter" type features such as the health bars and auto-facing.
If you look at the code and the amount of features it doesn't compare to PFE, so that's why it's free ahaha. Also, auto turnaround is already in PFE, look at "auto_turnaround_passive" 🙂
