It was a dll error if I remember correctly. Also, I couldn't use the shortcut, it was redirecting me to a Unreal Engine folder in my D: for whatever reason, and I don't have Unreal Engine.
The dll error might be caused because I didn't include the prerequisites for the game ( that if necessary will install the required stuff to run the game correctly ). But most PCs already have them so I excluded them from the files to reduce the file size.
The actual .exe file is just hidden in the same folder, I just hid it and made a shortcut because the actual exe file name is different from the game name 😄.
Anyway thanks for the info 🙂
