Create a physics-based arcade game similar to Bricks Breaker or Ballz! This game, in English, focuses on launching balls to break numbered blocks.

Core Mechanics:
- Players aim and shoot balls that bounce off walls and blocks.
- Blocks require a certain number of hits to break, determined by the number on the block.
- After each turn, blocks move one row down.
- The game ends if a block reaches the bottom.

Shooting System:
- Players tap and drag to aim, with a trajectory preview drawn while aiming.
- Upon release, balls launch in sequence creating a trailing effect.
- Balls return after their path completes, resetting the cannon position.
- Ball distance during launch equals their diameter.
- Ball radius is 2px for 20 or fewer balls and 1px for more.
- Balls are different colors.

Block Behavior:
- Blocks are 14x14px with numbers indicating durability.
- Blocks in Level 1 have numbers 1-5, increasing in each level, capped at 200.
- Blocks are densely packed.

Progression & Difficulty:
- Start with one ball at Level 1, reset to five balls from Level 2.
- Earn additional balls as you score, capped at 200.

User Interface:
- A recall button at the bottom center recalls all balls for re-shooting.
- The score display is at the bottom left.

Design Questions:
Block Motion: Smooth
Hit Feedback: Sound and score update
Theme: Black background, contrast colors

A physics-based arcade game similar to Bricks Breaker, Ballz, or Bounzy! The core mechanics involve launching balls that bounce off walls and hit numbered blocks, reducing their durability until they break.

Core Mechanics
- The player aims and shoots balls in a chosen direction.
- Balls bounce off walls and blocks, continuing until they exit the screen.
- Blocks have a number indicating how many hits they need to break.
- Blocks move down by one row after each turn.
- The game ends when a block reaches the bottom.

Shooting System
- The player taps and drags to aim.
- A full trajectory preview is drawn while aiming.
- When released, all available balls launch in that direction, one after another, forming a trailing effect.
- Balls return to the shooting position after completing their path.
- The cannon's position changes to the first ball that lands.
- The distance between balls during launch equals their diameter.
- Ball radius:
  - **2px** if there are **20 or fewer balls**.
  - **1px** if there are **more than 20 balls**.
- Balls come in different colors.

Block Behavior
- **Size:** Each block is **14x14px**.
- **Numbers:** Blocks start with numbers **1-5** on Level 1, doubling in each subsequent level but capped at **200**.
- **Arrangement:** Blocks are tightly packed, ensuring that balls cannot pass between them.

Progression & Difficulty
- On Level 1, the player starts with one ball.
- Starting from Level 2, the ball count resets to **5**, and players must earn additional balls.
- Players earn **+1 ball per point**, but the maximum ball count is **200**.

User Interface
- **Recall Button:**
  - Placed at the **bottom center** as both an **emoji and button**.
  - Clicking it instantly recalls all balls, allowing for immediate re-shooting.
- **Score Display:**
  - Located at the **bottom left**.

This version includes only the essential mechanics without additional power-ups, leaderboards, or monetization.
