Just a few things that would make the game a bit more realistic if you will. When you get a hotel, the property should show a red circle so you know which ones you have a hotel on. Also, should show how many houses you have on each property. Another thing, there should be a counter for how many of each upgrade you have purchased.
I am having issues with the wages. I click to take it up a level, it shows on the current wage rate, but production does not go up. Also, it is showing that it takes 0.00 coins/second. I didn't have this issue until I restarted.

Alright, it's been hotfixed now, sorry for all the trouble :)
