For such a large file size I was expecting alot more. Apparently you used a fixed screen size so the bottom hung off so I could see the bars along the bottom at all. There doesn't seem to be anything after I buy the 2nd line of upgrades. the lock seems to imply there is more but even after i sat back and earn bunch of money nothing else seems to be an option. So adding choice for screen scaling is a must. Adding more upgrade choices. And exit button.
