Chain Blast: Number Puzzle

Shoot numbered balls to clear them before they reach the bottom. Use power-ups!

"Gameplay Instructions
I. Core Objective & Failure Condition

Core Objective: Control the fighter jet to shoot the ""Number Balls"" descending from the top of the screen. Each hit reduces a ball's number by 1. A ball disappears when its number reaches 0. Eliminate all balls before they reach the bottom.

Failure Condition: The game ends if any Number Ball touches the bottom edge of the screen.

II. Basic Controls & Rules

Control the Jet: Use the keyboard arrow keys or touch-screen swiping to move the jet left and right. The jet automatically fires bullets upwards.

Number Ball Mechanics:

Balls display an initial number (e.g., 5, 10).

Each hit reduces the number by 1, and the ball's size shrinks proportionally as the number decreases.

The ball is completely eliminated when its number reaches zero.

Dynamic Change: The smaller the number, the smaller the ball's size and typically, the faster its movement speed becomes.

III. Power-up System (Three Core Power-ups)
Power-ups are obtained by hitting randomly appearing reward boxes or through point exchange.

Rapid-Fire Jet: Significantly increases the attack coverage area for a short duration.

Full-Screen Bomb: Detonates immediately, producing a significant effect when a large number of balls are clustered together.

Freezing Lightning: Releases an electric current to clear the Number Balls from the screen."
