Added Sound

Нello.

In this update, the sound of tower shots, blows and the death of monsters has been added to the game. A little cacophony for your delicate ears. You can turn the sound on and off with the notes button in the upper right corner, see the attached image.

Now I thought that it would be more correct to do this with a button with a speaker. I'll redo it next time.

Have a nice game.
