Yeah a few steps too much to expect people to do that just to play for few minutes. But I respect that you work with your own engine. Artsyle in your site and menu and background in game looks all very nice and climatic. Instructions for installation are clear for anyone who uses python. I would suggest to contact support of the game jam on their discord and ask for permission to build exe even after the deadline. They shouldn't have problems with it. Good luck :)
