So,everything worked and i tried to create moving background ( see in the video ) . As you can see the background is moving but suddenly when i am in menu and i press " start " nothing happens ( before it worked ) . And after i die and it swithes the scenes back to menu as you can see in the video the scene “brokes”,the scene from the game remains.Still cant play again …
Like i said,before it worked and now i have no idea what i did wrong
Sorry for the video being laggy,my pc is shitty as fuck.The unity runs properly,just the video is laggy
EDIT:i resolved the button problem,i deleted the eventsystem by mistake 
… But when i switch scenes the player and the enemies still remains there like in video ( last seconds )
I uploaded a picture with the problem too
