The wall, on paper.

Premise

There are no house levels. Every wall is authored by a player: a layout of bricks, zones and obstacles from a shared kit, a few rules, and a photo of their choice behind the glass. Everyone else plays it with a paddle and the lives the author allowed.

Kit

Four families. Bricks are what you break: glass, hard, steel, explosive, ghost, regen, magnet, rotor, key and lock. Zones sit on the open field and act when the ball passes through: slow, ×2, ×3, gravity, anti-gravity, a portal pair, a fake portal, a mirror, fog, a split that adds a second ball, and paddle modifiers — shrink, grow, invert, ice, sticky. Obstacles are not part of the wall: bumper, rail, fan, sweeping guard, trampoline, black hole. Rules are set once: lives, a timer, a wall that descends, a color that must fall first.

Every piece has a cost and a level has a budget. The player picks.

Speed

The ball starts calm. Every few paddle hits it gains a notch — the classic rule — and rapid rebounds build heat that adds more. Heat cools when the ball travels freely. Losing a life resets everything.

Publish rule

A level cannot be published until its author has cleared it and a flawless autopilot has cleared it too. Before that, the editor refuses what cannot work: unpaired portals, keys sealed in by locks, pieces in the paddle lane, more than one split zone, a wall over budget. Difficulty is allowed. Impossibility is not.

Background

For now, a photo. It is dimmed behind the field so bricks stay readable, and it travels with the level wherever it is played.
