Yeah I was impressed by how polished it seemed. Looks like it is by a different developer than the "Dig" games - https://store.steampowered.com/search/?developer=Thunderful%20Development
Still impressive that they've never made a City Builder before though!
The end of Demo said it'll be released this year (2023).
Yeah I really think they did a good job with having a lot of systems, yet still being pretty straightforward to understand. There were only a couple things that I didn't immediately understand (even without reading tutorial text).
Definitely can't wait to see if the full game holds to that pattern!
Good find! Definitely looks like they integrated the previous developer into their main team.
