The idea is awesome and the implementation is pretty good, though sometimes clients seem to kinda overreact :)
The robberies did not seem very challenging and are just minor inconveniences that just have you to press a button and the robber is gone. Also sometimes there are some mistaken fantom inputs that falsely accept the action when Im not finished yet.
Overall, great work! The game is straight to the point and implementation is well scoped so I do really think that you guys really have a great potential to become really great indie devs, keep it up!
P.S. And a slight tech tip for your future works or for polishing this one - check out 9-slicing for the sprites in Unity so that the corners dont stretch unequaly
