There are many people saying that under 1 minute easy attemps are cheating, I swear I havent and would never cheat, it just comes with practice and really fast fingers. My best times:
Easy - 0:39
Medium - 0:54
Hard - 1:09
Extreme - 1:28
Here are the best times I have achieved: Easy level - 1 minute and 3 seconds // medium: 1 minute 26 seconds // hard: 3 minutes and 30 seconds // extreme: 3 minutes and 20 seconds. Yes, I actually finished the extreme level much faster than the hard one. Funny.
