I have been playing this game for years and have only just started submitting my runs now, but I want to help with the classic levels. My best times are as follows 20-1.05 50-3.75 100-8.15 200-16ish There is one main glitch that makes it really easy to get fast at this game. When you enter the level you want to do, if you click the yellow tiles really fast, you can get consistently good times. You could bring your times down from 2.5 to 1.5 and below for classic 20. This also works for timed and endless classic. Also another thing to consider is the device you are doing it on. The wider the display, the easier it is to perform the glitch. I hoped this guide helped.
