suggestion: at every / each alley mission the player has 3 options / buttons (if he completed the requirement; if he didn't completed them yet, he will have only 2 options: "skip" or "pause"): "skip mission", "complete mission" and "pause mission". even on the computer some times, because the buttons are so close, you can miss click and press the skip mission when, in fact, you want to hit the "complete mission" button. But, on the phone, especially if u have big fingers like me, you missed the missions a lot. So, my suggestion is, either leave more space between buttons (more rows) or, EVEN BETTER, move them in one single lane, one button next to each other, of course with some space between them. This way you eliminate the possibility of miss clicking.
