This isn't a comprehensive setup list, because really who's gonna set this up other than me?

1. DL, install Godot /w C# support Visual Studio Code
2. Install .NET deps if not present

• .NET SDK 3.1 https://dotnet.microsoft.com/download/dotnet-core/sdk-for-vs-code
• .NET 4.7.2 Developer Pack https://dotnet.microsoft.com/download/dotnet-framework/net472

3. Godot settings

• Editor Settings -> Mono -> Editor -> External Editor = Visual Studio Code
• Editor Settings -> Mono -> Builds -> dotnet CLI

4. Visual Studio Code settings

• Install C# Plugin
• Install C# Tools for Godot Plugin

5. Set up tests

• Install .Net Core Test Explorer Plugin
• cp ./.mono/assemblies/Debug/GodotSharp.dll .mono/temp/bin/Debug/

This should let you run the project from Godot, probably.

It's playable online at https://moytw.github.io/SpaceDodgeRL/SpaceDodgeRL.html - however, I'm only going to push specific commits because the game's .pck file is apparently ~21MB? which is suboptimal. It's cool that I got it to run online though! The online version is significantly slower than even my laptop (and my laptop is not a snappy machine), to the extent that I'd have to actually worry about optimization if I want browser to be the intended experience.

Still it's really sweet that Godot makes it so easy!
