you need to do some jank to get this working as a download. first download the zip then go and download the windows version of godot exe here https://godotengine.org/download/archive/4.6-stable/. dont extract simplerpg. extract the godot exe and place both the zipped simplerpg and the godot exe in a folder. open command prompt in that new folder and run Godot_v4.6-stable_win64.exe --main-pack simplerpg.zip. game should run.
