alt Hacker NewsI'm developing a game in Godot using C# and my experience with it is very good. I guess it depends on how deeply you integrate with Godot. I try as far as its possible to write my game headless. My opinion may change when I have gotten to the point of actually shipping a game though, so this take needs a grain of salt.
For me the real headaches emerged when I started writing [Tool] classes in C# for scripting within the editor itself. I don't know enough about the lower level nitty-gritty stuff to explain it, but I basically had to close and re-open the editor every time I recompiled. It had something to do with not being able to load assemblies, for example if I had a Tool script which referenced a sqlite library. There were also some concerning instances of Exported properties losing their saved values, though in that case they can at least be restored from previous versions of the .tscn file from version control
