From what I've heard, that is only possible if both your computer and your internet connection are really good. Lag can also cause a player to win less often.
It's what happens to me. My browser and my computer aren't really good, so EP1 works good, but EP2 is lagging. So, that's why I continue playing EP1. :|
I admit, I like the uniplayer on EP2 more than the one on EP1, but the mechanics make it terrible. With the uniplayer on EP1 you had an advantage on it because of flow tap and the double and triple jump. But now on EP2, anyone can get a good time by just looking at a video on YouTube. Oh, and the pause glitch is still in EP2, so that'll help a lot.
