Yesterday I bought this game on steam, and I really love it. I found a slight gold bug though. While I was upgrading, (I expect I was doing it a bit to quick) my gold went below 0 instead of preventing me from upgrading. Currently I can upgrade everything to level 10 and my gold balance is at -3.4 million... Harsh debt! I assume whenever I get back into the plus it will act normally again. For now my gold is pretty much limitless. Might want to plug that money hole!

Felt like notifying this bug because it made the game way to easy early on.
