When the developers are working, as opposed to myself "typing", the progress bar goes off the screen and will not reset and give money until the 10 second delay is over and I can type again.
Every time I try to upgrade something on the "Upgrade" screen, I have to click it twice. It wouldn't be bad except that it takes the money both times but only gives one upgrade level.
The game was deleted by Kongregate mistake. Recently the game has recovered.
