making a game in 4kb is scary impressive, but not everyone has an atari in home (atari is probably not from my parents generation anymore, even they already have more updated stuff as childhood consoles lol), and not everyone wants to download an emulator they never heard about for a game...
So if I was you, I would also remake this game into more common stuff, like a webgl and a windows downloadable, because otherwise you will softlock yourself into a very specific and niche community
