Hey Casper, the demo has working CPU players for all the colors so you can play solo against every other color or just one, or play alone without fighting anyone.

In the  full release there will be full Solo-campaign mode :)

Unfortunately there is no way to "zoom" the screen. ALT+Enter works to toggle fullscreen.

Yeah.. well abandoned might be the correct term as there has not been any actual progress in few years but I promise that there will a progress update soon and an actual launch on some day :D

For online multiplayer we atleast have had great success with a program called parsec (https://parsec.app/)

Thank you for your longtime support :)
