itch.io

I think it's because the developers are updating and kicking player out of the game because I've notice that whole server just left and I think the developers don't think those symbols are important for the game so they just didn't make a font for it so you can't type it.

Maybe

It's the buggy anti hacks they pushed onto the server to combat the Eris Lotis hacker that hit a couple weeks ago on NA server.  They are aware of it and are working hard to iron out the bugs. The issue is the server, not your game.

im pretty sure the symbloes are blocked to prevent things like messing with the code since the no name glitch is just a line of code and should not work if the naming system was like any other game

The kicking bc of the update happens to me too

we can say ! / = - ; : ? ' and () as i know
