@Woodcat No. A non-constructive (a.k.a non-actionable) feedback would be "this sux, wtf are you doing?!?".
Freeman's breakdown goes into tight details of what is broken, why it is broken and what needs to be there instead. That is actionable, you can post on Godot website and socials about a paid position for a physics programmer and get this done. We need someone who knows C++, knows or can learn Godot codebase and has at least a basic grasp on game character physics. The hard research is done.
