All the "achievements" and "checkpoint" pop-ups pop exactly at the "precise" moment when you need to press the top of your screen,making you lose you streak 9/10 times... This is frustrating , very frustrating. Played this game 2014-2015 a lot and never had this problem. I just don't believe that the exact moment for those "pop-ups" is not intentionally synchronized in order for the player to be unbable to hit his targets.
