I fell like it would have felt and looked a lot better if there was a little more visuals, for example you could add some houses in the background or some cars, and make more of a visual indication that you sold ice cream. It might have been funny if you see an ice cream cone fly across the screen. Theres also an issue where you can buy things even if you dont have enough money, meaning you can make your money negative. Which really breaks the point of buying the increase sales by 2 or 4, since you can just spam buy the "Increase sales by 600" right off the bat. Overall good effort!
