sorry, i never saved a scratch project to computer before and i don't know how to download a scratch project and i can't convert it to any other file, so my project cannot be played, :(
i figured it out! i looked up a tutorial on youtube on how to do it, it told me to use this website called june beetle, i used it for one night at barmin's demo.

one night at barmin's: https://poopygames.itch.io/one-night-at-barmins
remember, one night at barmin's is STILL IN DEVELOPMENT!
