Unity cant run my simple game

(Hi, I’m new to unity, and I just made a very simple demo game using this video:

Everything works well, except one thing: When I want to play the game I just see a black screen. Nothing happens. What’s wrong?)

I found the solution, sorry I dont know how to delete posts (if it’s posible). :slight_smile:

Just for anyone else that has this problem, was it that you dident have a camera in the game xD?
