Hi,
I found your game really interesting, the basic mobile game but from the other side. It was pretty fun at the beginning, but it became too easy, I was spamming the most expensive stuff in the game, and I couldn't lower my money. I think you should add a goal to the hero, so the player can actually lose, and balance the game a little bit (like reducing the money you get every second). Great game.
Also, if you have rated my game, would help me a lot.
