Hey! The graphics of this game are pretty and I can appreciate how minimal you made the UI, though I think perhaps it is too minimal. Without an explanation, either in game, or in the description, it's not obvious to me what exactly im supposed to do to play this game: presumably build mines and parks/orchards to get coal and trees, then build various types of power generation buildings to produce power for the city. This was not immediately obvious to me, but could have been introduced somewhere in the game.
particularly, the UI in the bottom left corner seems to be performing double duty in both displaying the whole board's current stats and showing how a proposed move would modify the stats, however the way this is done is a bit confusing. It seems that when a tile is selected, all the bottom corner numbers go to 0, as in "you have not selected a building project, and thus, there is no change to this tile's stats," but in doing so, it is not possible to see what your current stats are, and vitally, how much money you have. I didn't realize that money was even a stat because, honestly, the bill didn't immediate register as money to me, and I never saw it display a nonzero number because I was always selecting a tile (and there is no way to deselect a tile other than to prompt the menu with escape). I think this could be fixed by always displaying the current stats but also displaying the costs/benefits next to the stats like "trees: 12-4" with the -4 in red like you have already done, so that the player retains the knowledge of the current stats and can compare proposed changes to it. If the only way to make money is to wait (as I suspect is true), then advancing the day could also display as a +1 next to the money.
