Super Mario Land/World 1

Part 1

 * Starting the game there is a ? block, conveniently placed overhead of you, jump to get the coin from the block.
 * Jump on the Chibibo that is coming in for the attack
 * Get the mushroom on this second ? block.
 * The next block over the hard blocks has a coin.
 * You can enter the next pipe to find a Bonus Room with 18 coins.
 * When you come out you'll reappear at the same pipe. Now go on and get the next coin in the block.
 * The next three blocks are all coins and stomp on the Chibibos there.
 * Then there is a line of 6 bricks. Jump and drop down to collect the 7 floating coins.
 * The block below has a coin, and use it to smash the fourth brick from the left and a hidden 1-Up heart will appear.
 * Then you'll find a power-up (mushroom or flower depending if you've kept your cool this whole time) above three bricks.
