Bus Suitcases: Stack Slide

This stacking puzzle revolves around managing luggage inside a bus compartment. Your core goal is preventing stacked suitcases from reaching the roof. Slide luggage pieces horizontally to fill empty spaces within lower rows. Fully filled rows disappear to reduce pile height and create extra room.

Game features:
- Simple left-right sliding controls for luggage adjustment
- Constant stacking pressure as new rows appear after every move
- Steady rising pile height raises difficulty over time
- Clean compartment layout for clear visual stacking judgment

How to play
1. Slide suitcases left or right to fit them into empty spots on lower rows.
2. Once an entire row is filled completely, it disappears to lower the stack.
3. A new row of luggage automatically adds to the bottom after every adjustment you make.
4. New bottom rows push all existing suitcases upward little by little each turn.
5. If luggage stacks high enough to touch the ceiling, the current game round ends.
6. Strategically clear rows quickly to avoid overloading the bus space for longer runs.
