The graphics are cute. But I'm just watching the shopkeeper work and occasionally pressing an upgrade button.
Right now, you can let the game run, go away and come back and press a few buttons.
Any feature like hidden bonuses to find, or click on a customer to serve the customer yourself, would change me from a "watcher" to a "player".
This is great. Its much more of a game now and could be quite addictive.
Some minor glitches: Your upgrades trigger only when I have more money than I need. It won't trigger when I have the exact right amount. Perhaps in Unity you typed > instead of >=. I'd recommend you reset your colliders (perhaps use a box collider if you're using a different shape) - I sometimes need to click on a few places before my click triggers.
