I'm a big fan of the way the scene becomes really erratic towards the end. The number taking over the screen was probably unintentional and just the way the UI was set up, but I still found it fun. Maybe having a X million, X billion, ... would help with knowing when I could / could not buy something. Otherwise its well put together and simple enough. Solid clicker that could be expanded if you wanted to.

I liked this game a lot! Great job!
