By the way, I want to say something
The buttons on the sides of the play button indicate different types of difficulty. If you do not touch them, it will be the easiest option. If you press the left one, it will be more difficult. If you press the right one, it will be the highest difficulty. If you need to turn them off, you can press them again (there will be a different sound similar to the sound of losing)
and in the menu has one secret button))
