Bus With Suitcases

In the puzzle game Bus With Suitcases, you have to keep the suitcases in the bus from piling up to the roof. Slide the cases left or right to fill up the gaps in the rows below. Complete rows will vanish from the stack, so keep going! You can't let the suitcases pile up all the way to the ceiling, yet for each move you make at least one new row of suitcases will be added to the bottom of the stack, pushing all the other cases up. Can you keep the bus from getting overloaded?
