So this project is/has been my introduction and learning of Godot Engine (4+). Yes, I'm another making the leap from U***y. So it's all mostly in C#. It's not been the smoothest ride moving over.
Anyway, hop you like what you see.
It is and has been quite an "adventure" getting this to run. I'm using C# Task threading to build the dungeon (That cloudy tunnel sequence). Biggest headache has been a well known "gotcha" bug where the your C# code in Visual Studio is rolled back by the Godot editor (a lot of effort lost at times, but I'm wise to it and I read the bug hopefully cured in 4.3).
