Hello, detailed info
1) Click on the setting(gear) button, then close it. Repeat the steps, 4-5 times or even more. (This is from dev side)
2) By multi touch, I mean.. use 2-3 fingers to rapidly tap on the pieces below. As if you are playing a piano. The pieces end up with the wrong size + part of the pieces overlaps each other. (Most players won't try to break the game that way, but I will •_•, hehe)
3) By restart, I mean. Close the game, and launch it again on your phone. While your logo is still playing.. keep tapping (multiple times) exactly where the buttons will appear in a few sec.. e.g in middle on the screen. After your logo ends, the gameplay will be launched even if my credit is 0)
About the crash, it might have happened, bcz your leaderboard was taking time to open, so I might have clicked the other leaderboards few times, then "home" during that delay.
I was free today, hence the time to test your game. Not sure I'll be that free soon.
