the times you have to beat are ridiculous, i do what i think is the very best i can only to be 0.16 of a second off? games that require such pixel perfect precision get boring rather quickly,
We know that the challenges are a bit hard. We took the best time we could get and added 1-2 seconds on most of the levels. We will change the challenge times in the next update maybe.
