A classic of 1.9 and of my favorite levels of all times. I may be biased as I'm way too familiarized with this level, to the point a practice run took me 7 attempts and then I beat it on my first try, but honestly you should only worry about the first ship and the first ball, everything else is a walk in the park and even the memory aspect of this is easy to distinguish; fakes have a different outline than the actual line color.
