So first you start out in a normal world. Use the arrow keys to move left and right and the buttons to run and jump.Go through the stage until you reach the 4th pipe. Enter the pipe and exit through the other pipe. Congrats, your now at the end of the stage! Just climb the stairs and grab the flag. Now the second stage, A small cut-scene will play and it shows Mario going through the pipe. As soon as you touch the ground make a break for it until you reach a part where there's a one block gap and enemies are going through it. Wait for the koopa and jump on him then kick the shell to kill the others. Continue moving until you find the platforms that move up and down. Go to the ones that move up. Wait until your near the top of the screen and jump over the blocks and pipe. Move right to reveal a secret warpzone. Go to the pipe that has the number 4 above it and go in. Now for the first stage of world 4 there's not much to say just be like sonic and run for it. Its possible to jump over the pipes with piranha plants coming out of them with good timing. Keep running till you reach the end. Grab the flag and now your on to 4-2. Once again a small cut-scene will play. Slowly jump on the blocks until your on solid land. Soon you will see the moving platforms Also there are two blocks near the platform. The left block is a vine to climb up. There are secret blocks underneath the block with the vine. Hit the secret blocks and climb your way to the vine block. Climb the vine and move right to reveal some mushroom blocks and coins. Soon you'll find another warpzone! Go down the one that has a number 8 above it! NOW YOUR HALFWAY THERE! OOH OOH LIVING ON A PRAYER! *cough* Ok, back on track. With 8-1 you just have to run through it. There's no secret strategies to help you. With 8-2 at the beginning wait for the parakoopa to come down and make your way to the top of the stairs and run. After this part you just keep running. It's a relatively short stage. 8-3 is another just get it done stage. All I have to say on this stage is jump over the hammer bros and its also a relatively short stage as well. Now your on the final stage. This stage is a pipe maze. To get to bowser you need to go through certain pipes. What? You don't know the order? That's what I'm here for! As soon as you start the stage jump over the lava gap and (you guessed it) run. As soon as you jump over another lava gap go through the first pipe you see. Now keep running until you see a pipe supposedly unreachable. There are some secret blocks left of the pipe. Hit them then climb them and enter the pipe. Now keep running and avoid the flying cheep cheep Enter the third pipe (the one right before the lava gap). Now your in a underwater segment. All i can say here is stay on the ground when you can. Enter the pipe at the end. Now your so close! Just avoid/kill the hammer bro, time your jump so the fireball doesn't kill you, and finally, time a jump so you can go between bowser's hammers.Hit the ax at the end of the bridge. CONGRATULATIONS! YOU JUST BEAT SUPER MARIO BROTHERS!!!!!!!!!
