Thank you all for the great and constructive feedback, especially @UnitPeka!
I took the last week and transformed a TON of the game.
The biggest thing I did this week:
I created 8 unique maps, each with its own custom land, challenge, and building that unlocks when you reach the map. (So you unlock the Fire Station when you reach the “Arson” map, and then going forward you now have access to the Fire Station to build in your cities)
I’ve balanced out all of the buildings JaeThi mentioned - so now everything “makes sense” in terms of upgrading to more costly buildings, and they add more value per $.
Income used to be very basic - just keep spamming buildings for more money. Now, you’ll need to get enough workers to create a Business and the services your people need will cost you money!
I also made the happiness system more dynamic and involved - instead of just requiring a building of a certain type, you need to get a certain level of coverage for your city’s needs. For example, a restaurant covers 100 citizens, so if your city has 350 people, and you only have 3 restaurants, they will start to get a little grumpy about not having enough restaurants.
And finally, I added new disasters including buildings catching fire!!
So thanks, again, for the feedback! Without it, I wouldn’t have gotten the spark that inspired me to spend this week transforming this game into, what I think, is now a richer and engaging experience.
