I don't know if you already said how, but is it possible to get WIP chars in the current game as playable? I use linux to play it, so another question i have is, do i have to re-download the game for updates when they roll out? I am a noob when it comes to this
Yes and no, This version the version you get from the itch page isn't set up to accept the WIP characters. You'll have to download a new version of it from the Patreon & Discord with the WIP already included. After doing that, minor updates can just be character files which you drag and drop to overwrite.
