Layer Tower

I. Core Game Objective Control the size of building floors with one finger, stack floors with precision to build a skyscraper, challenge your highest floor count and all-time best score, and create your very own city skyline. II. Basic Controls All actions can be completed with just one finger on the screen: Press and hold the screen, and the current pending floor will expand evenly outwards at a constant speed. Release your finger, and the floor will immediately stop expanding, lock in its current size, and fall vertically to complete a stacking action. III. Core Game Rules Foundation BoundaryAt the start of each round, there is a fixed foundation with a standard size, which serves as the maximum allowable boundary for all floors. The final size of any floor must not exceed the scope of the foundation. Valid StackingWhen the locked size of the released floor is fully within the foundation dimensions, the floor will land securely on the structure below. You will successfully stack 1 floor, your floor count increases by 1, and the game automatically progresses to the next round of floor generation and resizing. Invalid Placement PenaltyWhen the locked size of the floor exceeds the foundation boundary, the portion that extends beyond the foundation will break off and collapse immediately, while 1 health point will be deducted. The remaining valid portion that fits within the boundary will fall to become the new stackable floor, and the game continues to the next round. Health SystemYou start each round with 3 default health points. 1 point is deducted for each invalid placement, and there is no way to restore lost health points. IV. Game Over Conditions The round ends immediately when either of the following conditions is met: Your health points are reduced to 0. After falling, the floor makes no valid contact with the already stacked structure below (completely suspended), which is judged as a stacking failure.
