Sintopia got a new, refreshed demo on Steam for the Steam Next Fest (available June 4th), with an extended demo period, currently until at least the middle of next week
In this edition, you can try the “Challenge” mode with hell control and random objective system, launch the new magic Magmine, customize keyboard shortcuts, and enjoy a lot of interface improvements and gameplay balancing.
Sintopia promises a combination of satirical "God game" humor and deep system management elements - the demo is definitely worth trying
