Thanks! The idea is that on the first level you want to try get as high of a score as possible and then get lower every other round!
The aim is to get as high of a score as possible overall without ever beating your previous rounds score. Your high score is calculated by adding each of your rounds scores together at the end. I do think this could have been explained better!
Try playing like this where you aim to get as close to your previous score as possible without ever beating it.
