I gave it a try the other day and really enjoyed it! Really nice cartoon art style / setting. The above-ground portion of the game feels like a solid clone of the Anno series games. Then below ground adds a fun twist of exploration / resource gathering into the mix.
Really looking forward to when it releases now!
Interesting, I looked into it briefly and found this:
2020 - Image & Form, Zoink and Guru Games are merged and fully integrated in Thunderful Development AB
There was a merger, but maybe not entirely different developers.
Good find! Definitely looks like they integrated the previous developer into their main team.
