Short but definitely fun, although I wish there was a gallery mode so you could view the customers' weight stages after you beat the game. Or a way to repeat levels so you can try for a perfect score to see customers at their max weight (since their weight gain seems linked to score?)
It's mostly because the game is super hectic, especially when you have the asteroids modifier or the zero-g modifier, it's easy to screw up an order or take too long fixing it.
