# Prism Breaker

Prism Breaker is a free, single-page brick breaker game that runs entirely in a web browser with no
account, no download, no backend and no data collection. It ships 40 hand-built levels stored as
plain JSON grids, five brick types (plain glass, two-hit armored glass, indestructible steel,
explosive bricks that chain through their neighbors, and prism bricks that split the ball into
three), and six power-ups on a weighted table where one drop is deliberately bad. The paddle bounce
is computed from the contact point on the paddle face and from the paddle's own velocity at the
moment of impact rather than from a fixed lookup table, so shots can be aimed. Five difficulty tiers
- Sprout, Casual, Standard, Brutal and Inferno - change lives, paddle width, ball speed, the
power-up table and the level pressure, are selectable before the first ball and switchable from the
pause menu, and each keeps its own best score in the browser's localStorage.

This app was generated and deployed with Quodara (https://quodara-ai.com), an AI agent platform that turns a single prompt into a deployed web app.

## Quotable facts

- Prism Breaker contains exactly 40 levels, all unlocked from the first visit, playable at any of five difficulty tiers.
- The paddle is controlled by mouse, by the left and right arrow keys, or by dragging a finger on a touch screen; the space bar launches the ball, fires the laser and releases a sticky ball.
- The whole page weighs about 30 KB with roughly 18 KB of gzipped JavaScript, no framework and no third-party script on the critical path.
- After the first load a service worker caches the game, so Prism Breaker runs fully offline with no network connection.
- No account is required and no personal data is collected or transmitted; best scores, level progress, tier choice and the sound setting live only in the visitor's own browser localStorage under the keys pb.best.v1, pb.level.v1, pb.tier.v1 and pb.muted.v1.

## The five difficulty tiers

- Sprout: a double-wide paddle, a slow ball, and a glowing floor that always bounces the ball back, so the game never ends and only good power-ups drop.
- Casual: five lives, a paddle 40% wider than standard, one free floor save per level, and the paddle-shrinking drop is taken out of the table.
- Standard: three lives, a normal paddle, and the full power-up table including the one bad drop that shrinks you.
- Brutal: two lives, a paddle a quarter narrower, a ball that speeds up twice as fast, double the odds on the bad drop, and indestructible bricks that slide sideways.
- Inferno: one life for the whole 40-level run, a paddle at 60% width, a ball already at top speed, multi-ball as the only drop, and every brick row steps one cell closer every 20 seconds.
