Happy Collision app for iPhone and iPad

Happy Collision is a small game that tests your eye observation ability and hand operation ability.

The current version includes simple mode and difficult mode.
In simple mode, two different small cards will randomly fall from the top of the screen. You need to click the button at the bottom of the screen to switch between the same cards, and you will get a point for each success.
In difficult mode, four different small cards will randomly fall from the top of the screen. You need to click the button at the bottom of the screen to rotate to switch the same cards together. You will get one point for each success.
As the score increases, the speed at which the cards fall will also gradually increase, which will further test your resilience.

Invite your friends to play together and see if they can beat my record.
Hope you can enjoy this little game.
