So sadly Flash is pretty dead these days which also makes this hard to play :(
If you want to try to make it more accessible, I do remember seeing a Scratch to JS converter here. Give it a shot maybe?
I'll try it as soon as possible!
I do not use (JS Scratch) phosphorus to exe because it brings some bugs, and Flash has no bugs running Scratch projects and will be fullscreen if you set it to while converting. I only use phosphorus to exe on big games that would lag on flash.
