When ever I send someone the exe to my game, It's just a gray screen, I think I've fixed it but I'm having trouble getting people to test it. If you would help me out a ton here, and test it, I probably won't give you anything: https://loffyyytoffyyy.itch.io/snow-haven

Sounds like a graphics issue. If it works for some people and not for others, feedback is not gonna solve this, as you already know it works for some people and not for other people.

My guess would be issues with that Vulcan thingy.

Don't know why people hated that I posted a exe but there's now html which kinda defeats the whole purpos

Try the Godot forums - most likely others have encountered the same issue and can tell you how to fix it.  Here, it's random whether a Godot expert will see your post or not.  But it might help attract the right person if you include in your title that the weird bug is to do with a Godot .exe.
