Your ship automatically cycles through four lanes. Hold Space or the pointer to lock the current lane, advance and shoot. Destroyed enemies leave gold: keep advancing to catch it and raise your multiplier. Missed gold makes that lane faster. Any enemy reaching the left edge ends the run. Tap after game over to retry.
