Hi! thank you for your interest!
Right click on the compressed folder and there should be an 'extract' or 'unzip' Once done look for the icon that says 'game' click that and it should open up for you!
That’s probably a glitch on my end my apologize I’ll try and get if fixed and post an update soon!
Sometimes when the program makes a deployed version for people to play it will bring tonlight glitches not present in the game dev side of things I probably should have check the the downloadble build my bad
