I am quiet new in the game, but I like the principle, and I am sure this game as potential. As a newbie, it is really hard to understand where my money goes.
I discovered the cash chart, which is very good to see the cash flow, but this will be very useful to have a column with a little description of what this expense/revenue is for.
One more think, I am not a huge fan of this tablet UI, it is not very user friendly in my opinion, plus it does not work properly on phone(no way to scroll down)
Thank you for your game, and good luck in your dev
