Very nice game, well polished, with nice touches from the loading screen to the kinetic balls... As many have said, I would start off slower in the beginning with fewer shoppers as we familiarize ourselves with the game and ramp up difficulty as the game progresses. I'm guilty this myself; I'm in the codebase everyday and I know the mechanics like the back of my hand so to me it seems easy, but to a new player, they still need the slow ramp up to keep them hooked, so they go from "This is easy!" to "Okay, now it's challenging!" But nice job!
