[Important] Regarding the Issue of the Game Running at High Speed

We have received reports that the game may run faster than intended on devices with high refresh rate displays.

We are currently investigating the cause of this issue and, at this time, cannot provide a definitive solution. However, lowering the refresh rate to 60Hz in your device's display settings may resolve the problem. We apologize for any inconvenience and kindly ask you to try this solution first.

■ Issue with the Game Freezing on the Results Screen
If the game freezes on the results screen in Challenge Mode or Endless Mode, please try logging out of Play Games from the leaderboard screen.
