I started off by only scamming people a little bit, but quickly realised that you can only make any progress by scamming to the max. The upgrades were of the stalls were funny and it was a nice touch that the roofs indicate their levels. Though, the music was kinda annoying (no seperate sliders for sfx and music).
There is a lot of potential for expanding the game. I would like to see some income management. For example, you hire guards to walk around; instead of bying them (for life?). Restocking stalls also doesn't cost any money. I don't know if how much you scam influences how quickly stock runs out, but I think this should be the case.
In the end I manage to get the humble unfair park pictured below.
