## What it is

Brick Blaster is the classic Breakout / Arkanoid loop, scaled out into an
endless-level neverending run. Free, no signup, no install. Plays on
phones (portrait), tablets, foldables, desktops.

## Mechanics

- **Field**: 360×480 internal pixels (3:4 portrait). Stage scales fluidly
  from 320 px phones up to 420 px desktop max; physics math always runs in
  canvas-internal pixels.
- **Paddle**: bottom of the screen. Hit angle is determined by where on
  the paddle the ball lands (left edge → angled left, centre → straight
  up, right edge → angled right).
- **Brick grid**: 8 rows × 7 cols every level (56 cells). Tier mix
  varies per level (seeded).
- **Lives**: start with 3, hard cap 5 (only the `extra_life` power-up
  raises the cap). Ball-out → respawn glued to paddle.
- **Levels**: clear all bricks → next level. No level cap.

### Brick tiers

| Tier  | Hits | Base value | Visual                       |
|-------|-----:|-----------:|------------------------------|
| std   | 1    | 10         | accent-coloured (theme)      |
| hard  | 2    | 30         | yellow → ochre as it cracks  |
| tough | 3    | 60         | orange → dark red            |
| armor | 4    | 100        | silver → grey shades         |

Per-level multiplier `1 + 0.1·(level − 1)`. So a `std` brick is worth 10
at L1, 19 at L10; an `armor` brick is worth 100 at L1, 1090 at L100.

### Power-ups (drop from broken bricks)

- **multi_ball** — splits the active ball into two; each child can split again on the next pickup.
- **laser** — paddle fires a vertical laser pulse on a short cooldown for the duration of the buff.
- **wide_paddle** — temporary +60% paddle width.
- **speed_up** — power-hit; next paddle contact launches the ball at +50% speed.
- **through_ball** — ball ignores brick collisions for a window, punching a tunnel through the field.
- **mega_bomb** — detonates a 3×3 area on the next brick the ball touches.
- **slow_time** — temporary 50% time scale on physics; rescues a runaway multi-ball.
- **extra_life** — +1 life, raises the cap by 1 (the only way past the 3-life floor).

## Modes

One mode: keep going as long as your lives last (or hit the 30-minute
safety cap). Difficulty escalates automatically via the brick tier mix
formula:

```
hard  = clamp(0.05  · (L − 2), 0, 0.30)
tough = clamp(0.025 · (L − 5), 0, 0.17)
armor = clamp(0.012 · (L − 9), 0, 0.08)
std   = 1 − hard − tough − armor
```

By L17 the mix plateaus at 45% std, 30% hard, 17% tough, 8% armor.

## Determinism + anti-cheat

Brick Blaster's physics is floating-point — bit-perfect cross-platform
replay isn't viable. Anti-cheat is **sanity caps + score-economy parity**:

- `score / brick` must fall in `[10, 2100]` (min std @ L1, max armor @ L200).
- `MAX_SCORE = 5,000,000`, `MAX_BRICKS_BROKEN = 10,000`,
  `MAX_BALLS_LOST = 50`, `MAX_LEVEL = 200`,
  `MAX_PADDLE_HITS = 100,000`, `MAX_DURATION_MS = 30 min`.
- Event-log brick-event count must equal `bricks_broken` ± 1.
- Out-of-bounds values are rejected on submit.

The full event log (every brick break, every power-up, every paddle
input) is recorded in `brickblaster_runs.event_log` so any suspicious
run can be re-played manually.

## Controls

- **Keyboard**: arrow keys / A·D move the paddle, space launches a glued
  ball, P pauses.
- **Mouse**: paddle follows horizontal pointer position.
- **Touch**: drag anywhere on the canvas to slide the paddle, tap to
  launch.
- **D-pad**: optional on-screen four-arrow pad for thumb input.

## Privacy / signup

- No account required. Guests get an auto-generated username on first
  visit; rename anytime.
- No tracking pixels, no analytics SDK, no third-party scripts.
