Hey, I've been trying to play this but it just crashes on startup. Any advice would be awesome
You could try running the game from the windows command line, or the terminal if you're on linux. There might be an error message there pointing to what the issue is.
Also what are your system specs? cpu, gpu, operating system, etc.
One of the new Radeon drivers for AMD gpus broke a lot of Vulkan based Godot games for some users, so you might have to use the dx12 version if that's the case.
