Hey, when I click on create Installer and then do the install it creates a shortcut and then the game itself, hidden somewhere within my program files. Is there a way to turn it into a simple .exe, without the need of other files and folders?
It is possible to create a standalone game with an exe file that can be executed anywhere. But it is not recommended to use it since it's not guaranteed to work when shared to other computers. Only the installers are stable enough to be shared.
If you still want to do it read the last bullet point about standalone executables in the "readme" file under Test & Build.
