tic80 is pretty limited too. It's more expansive than pico 8, but when it comes to stuff like importing stuff, etc, it's still a bit limited. There's a person called borbware- https://twitter.com/borbware who's working on a tic80 steam game.
He says he wants it to be the first tic80 steam game and no one wants to contest it, so I guess you can dm him for details or questions regarding steam
