💥 Ballistic Barrage

Aim. Launch. Obliterate.

A fast-paced browser arcade game where you fire a volley of balls to smash descending blocks before they reach the bottom. Every turn the blocks get tougher — and stranger.

• Each turn a new row of blocks slides in from the top and everything shifts down one row.
• Break blocks to score. The score for each block equals its HP — tougher blocks are worth more.
• Collect the green +1 orbs to permanently add a ball to your volley.
• Game over when any block crosses the bottom line.

Block Types

Block	Indicator	Behaviour
Normal	—	Standard. Break it.
Armored	Gold border + ◆	Needs 2 hits per HP point. Shows a crack after the first absorbed hit. Appears from turn 2.

Scoring

• Breaking a block scores block.maxHp × comboMultiplier.
• The combo multiplier builds when you break blocks within 1.5 seconds of each other — x2, x3, up to x10. It resets between turns.
• Chain explosions from Explosive blocks count toward the combo.

Warnings

• Blocks in the last two rows pulse red — act fast.
• The ball count in the HUD ticks down in real time showing how many balls are still in the air.

Three files, zero dependencies:

index.html   — DOM structure, HUD, overlay screens
styles.css   — Layout, UI, animations
script.js    — Everything else (12 sections, ~1 200 lines)

script.js is organised into clearly labelled sections:

1. Config & Constants
2. Audio Engine (Web Audio API synthesis — no samples)
3. State Management
4. Canvas / Renderer Setup
5. Input Handling (mouse + touch)
6. Physics & Collision (fixed-timestep with substeps)
7. Level Generation
8. Particle System
9. Game Loop
10. Rendering
11. UI Helpers
12. Init & Bootstrap
