@starry-abyss no worries! I actually have never released anything on HaxeFlixel with non-trivial performance requirements. I'm really grateful for the time and energy you put into explaining it to me until I finally "get it." So, thanks again.
I'll probably get a chance to work on this later tonight. I'll move my code into revive and if (for some reason) it doesn't work, I'll report back in this thread.
