[Free] Doors

To the dev. Since the last update I've had alot of trouble selecting things on the screen. I started over from level one for my mom and it was a nightmare just trying to open the door after the puzzle was figured out. Swiping etc was also difficult. Got trouble in the later levels too
 
level 46 is nothing more than a metronome? if so, why the hell did I have to be born without rhythm
