Hello Random Ideation Studios! Thanks for playing the game and for the positive feedback! I used inno setup to make the setup.exe file. Here is a tutorial to make it easier for you to understand:
You will have different files comparing to the ones from the video. You will make a file for the "Game Data", but you have to make a different one for "Game Mono" too. You will understand better after you finish the video. Also, the "UnityCrashHandler64.exe" and "UnityPlayer.dll" must be in the same folder with your game executioner. You have a photo of my folder looks like. That are the files and the folders that will go in inno setup. If you don't understand or you are having problems, fell free to dm me.
