BreakOut

Operation / four rules

1. Launch is a choice

   The ball leaves the paddle at ±30° off vertical, alternating each life — never straight up. Tap, click or hit space to fire.

2. Where you hit decides everything

   Contact within ±1px of the paddle centre sends it vertical; the tips throw it out to 65°. Centre, then edges, is how you carve a tunnel.

3. One brick per frame

   The ball sweeps in sub-steps and resolves only the nearest AABB contact, so it can never clip two bricks and cancel its own reflection.

4. Speed never drifts

   Every bounce re-normalises the vector to a constant 3.44 px/frame with a vertical floor — no horizontal ping-pong stalls.
