Issue with Simultaneous Taps
We are aware that simultaneous taps may not register correctly on certain devices in the new Dimensional Arcade (Concert of Champions) mode.
To fix this, activate the Disable Simultaneous Enemies option in the Dimensional Arcade settings. This replaces simultaneous enemies with a single enemy approaching from the right.
How to enable this option:
Tap the Dimensional Arcade icon on the Home Screen. (Note: If this is your first time playing Concert of Champions, you must complete the tutorial first.)
On the stage select screen, tap the Settings button (gear icon) in the top left.
Check the box for Disable Simultaneous Enemies.
