Bug fix

When I was writing my own button to maintain the same similarity with the PixiJS version, it was necessary to program my own button due to layout reasons. I discovered that this caused an issue where the button was clickable even when it wasn't visible, which resulted in restarting the game or going back to the main menu.

Who would click when the game is controlled by a mouse? 

On Android, a touch event is called first before a drag event.
