Mirror Room Glow Up

Ok, I made a mirror room using Godot and had a lot of trouble with my model orientation. Basically the player was upside down with the camera behind him. Found a script that worked to follow the player no matter what, but other problems arose with movement then being opposite to what it should  be (left=right, up=down). Found something to fix that, then realized if I added other NPCs, later down the line it would again become a huge problem. So I shifted to Unity!

I'm having trouble getting the movement back to the way it was before, but I've upgraded the room quite a bit, I think! Do you guys like the changes? Thanks for looking!
