The swimming pool appears to be sold for $10,000 but when I attempted to buy it (with $10,000) in my inventory, nothing happened. Is the list price wrong?
I would add an upgrade to the bank that allows you to automatically collect the interest. This is an idle game after all, and that would allow you to earn money while idling more effectively.
Excellent game, loved the music, gameplay, and the simplicity. Just two complaints, the text in the upper left could have appeared at the beginning of a level, then gone away. There were also several glitches that made it very easy to beat a level. Other than that, great game.
