Right click on the shortcut to the game, choose "Properties" and the line Target will look something like this: ["C:\Program Files\Amazin\Amazin.exe"]. Add the word window to the end of that line, after a space. If that line is in quotation marks like my example, you want to be outside the quotation marks. So you end up with: ["C:\Program Files\Amazin\Amazin.exe" window]. Then hit OK and it should work!
Of course your actual folder names will vary, don't change what you have.
