Discord?

I can't find a valid discord anywhere for this game

Game's discord server is 'Thylacine Studios', iirc.

You can find all the important links related to this game, including their discord through the pinned discussion post posted by the dev himself. The discord link still works the last time I checked it.

Also, while this probably isn't relevant to your case, last I remember Discord doesn't tell you if the reason you aren't finding a Discord is because you're banned from it.
