Other details: At the time I saw that game, it was in early development (Early-access/Alpha). There were performance issues with the game so I decided not to buy it. After a year or so I wanted to check up on it and I could not find it even though it was on steam. I'm a big city builder player and the game had potential so if anyone can help me find the name I would be grateful.
