Well, BlueBishop and Stripes are working on porting FS as a whole over to Flash, to make it easier accessible. Other than that, I don't know of any other FS flash projects.
Btw, you can find the three flash dress-up games (plus another dress-up outside FS) and various pieces of FS-adjacent artwork (from the Joe's #1 Fan story that got merged with an "8 years later" FS storyline after a few chapters) on
my FurAffinity page.
