Hi explodi. I've been trying v.1.12 for 1-2 hours now. I started developing differentiated income tax! great add! Did you change other parameters? Rent prices have been dropping dramatically since the new update, by a lot! Was there also a bug regarding tourist numbers? My city was showing 0 tourist for years but hotels were full, I noticed this number "exploded" after the update. Similarly with workers on factories. I tried factories at different times, but they failed every time, now they seem to develop gradually (same with supermarkets). I'll keep playing and give some feedback.
But I love the changes you made on the way graphs are shown, the new organisation in categories and sub-items, the new tools you added. I would love to see more of them in the future (e.g. tax cuts for certain businesses and or for employing certain groups -like long time unemployed, disabled or women (if there is any difference between them in the game?), differentiated auto fees for electric / combustion cars, etc).
Have a great week!
