I am working on repairing the problem, and I am trying to make the program just an EXE instead of the installer! Only problem was that my compiler had some problems, but I will try again!
To draw pixel art you can use programs such as piskel! Link: https://www.piskelapp.com/
Furthermore, the name of the installer by default I think is either ‘Made in GameMaker Studio 2’, or ‘STICKY JUSTICE - SHENANIJAM 2018’
