Break the wall. Pick a perk. Break the next one.
Keep the ball in play with your paddle and clear every brick. After each wall you choose one of three perks, and they stack. Every fifth wall has a core that moves and fights back.
Phone: the paddle follows your finger. Tap to launch.
Desktop: move the mouse, or use A/D or the arrow keys. Space or a click launches. P or Esc pauses.
Pick a perk. It lasts the rest of the run.
Your run is saved at the start of each wall.
