Redcode is kind of a bonkers assembly language too. I never really got into it because it’s kinda boring, but I could see this being crack for the right person.
Space Engineers in dev mode also permits player coded behavior. The player may write scripts in C# and apply them to game objects. Scripts run in a sandboxed .NET environment.
I've definitely spent time in the past looking for a game probably exactly like this! I figured surely someone made this.
I'll definitely set that aside to delve into later.
Thanks!
