Cool idea but flawed.
For one, the controls seemed to be a little sloppy. Was it just me, or were they inverted on the right screen? That's not usually a good idea :P
Second, at times I would just stand at the counter and hit space in front of some guy like 50 times and watch my money go up. Why was that?
Another thing: I didn't understand what was happening. A quick brief of what was going on would have helped immensely.
Other then that: it was a cool game, with a great concept. It just needs a little bit of beta testing and cleaning up.
