I would like to see Adjacency bonuses be a thing from the very start, and be based on how many sides are touching. Maybe a 1-4% production bump per building that is touching the other building. When I realized it doesn't matter if they touch at all, I was pretty disappointed. I feel like not encouraging tight placement from the very beginning is basically taking that "tetromino" shape and wasting its potential, but meh, it was still pretty fun for a while. I still don't feel super compelled to finish as I don't feel like I am doing much other than placing the pieces in the correct order to get the stats to go up. If there was some way to demonstrate mastery through placement mattering (especially during the super long tutorial) I would keep playing.
