questions in Undertale MULTIPLAYER

hey amolio, do you use gamemaker servers for the multiplayer. or you use a different platform for it.
ok, since ive seen the post about the alpha version, is it a early access or just a dev progress. or you can get playtest. kinda confused rn.
Do you guys plans on allowing people to add they own characters in the game with a temple we can use?
will you add Custom Accesories? like will you able to make your own one
Would you be able to become a regular monster from the underground? Like become a froggit, loox, washua, and other stuff?
i wonder, if in the game u can make attacks one day, would u be able to make attacks that work like sans'es final attack in undertale or not?
In Underboard, how do I get more coins when I don't have enough to make more posts?
