Hello, thank you for the compliment!
To be completely honest, there are a LOT of things I plan on editing into Godot (For example we are ripping out the multiplayer for a custom system that can handle hundreds and potentially thousands of players in the same space) so it made sense to make it into a fork!
The systems can still be ran with Godot as plugins as well, and after trying to do similar with another game engine but being waved off kinda rudely i'm honestly overall just interested in making what I think an engine should have and later sharing it if anything!
