Cute game! And some great ideas too. I enjoy the concept of the gameplay loop, and reading some of the other reviews and your replies I can see that you have some great plans to expand upon it, which would be awesome!
As far as feedback goes, I did have some difficulties with the UI. There was a point where this was happening and the game locked me out of actually selecting any of these. 
I had to restart and go through the intro dialogue again, which dragged a bit as you can skip the initial type out, but you can't skip the backspacing. I otherwise had an issue where I would try to buy things and the quantity owned didn't seem to update but money was being withdrawn, so I'm not sure what the go is there.
I think the experience could be smoothed out by having the game pause (or disable character control) when there are menus on the screen. But otherwise, with a bit of polish, I think you've got a neat, engaging game on your hands! Good work! Keen to see where it goes.
Cheers!
