It doesn't matter if this step count (284) is optimal or not, your last 2 levels are pretty fun, of course you should continue this series, good luck in advance for your next levels =)
I thought when I tested it and it perfectly hit 400 was satisfying and then Andre messed it up. All jokes aside good job on beating me. It is pretty easy to do. BTW let me know if I should keep going with the series and this goes to everyone not just to Andre.
