I walk into the basement. There’s a bright red door on the wall. I open it and step inside. It’s dark at first but then my eyes get used to the light from the screen. I’m playing Super Mario Bros. on the Nintendo Entertainment System.

The sound of the level starts. I jump over bricks and avoid goombas. The level is long and full of blocks with coins. I find a hidden block and see a mushroom inside. When I pick it up, I get bigger! I stomp some goombas now because they’re smaller. I walk onto a moving platform and it carries me to the top.

I reach a castle gate. Inside is Bowser’s first level. I rush through, trying not to fall into pits. I find a key and open a door. Now I’m in Bowser’s room! He looks huge. I hit him with my hammer and he disappears. I get the star power and run away as Bowser comes back.

I collect the last coin and go back to Mario. I press A and Mario transforms into his big size again. I jump up and down on the switch to open a door. Inside, I find three switches that make different things appear. I figure out which one is right by trial and error. When it’s just right, Bowser appears! I hit him with my hammer and he disappears.

I win and go back to Mario. He thanks me and gives me a power-up. Now I have fire breath! I can’t wait to use it in the next level.
