Just to confirm that demo versions were uploaded to Itch dot io in late april so just search the project name on the main page and it should appear.
The single player part should be stable and ready if anybody wants to test it, currently doing fixes on the local multiplayer.
The next post will be when I upload the demo to Steam.
(Not that anybody reads these updates anyway (but at least I'm consistent enough to write them. (Too much depth of parentheses? (Nope!))))
