There’s also an upwards flick when you stop scraping which
will send your spiral into the air. This is how you canhit the bonus boxes that
pop up — getting the timing of your release right is key to getting the best
points. As soon as your spiral has knocked down a wall, you can start scraping
again, even If there’s still rubble around. The more scraping you do, the more
points you get, so get grinding as soon asyou can to get those combo bonuses
going up.
