New Super Mario Bros.: 7-7

This is an automatic sidescroller. Making life more interesting are the numerous donut lifts. The first Star Coin is near a ferris wheel platform. There are platforms moving left and right, and will pass past walls, so you might fall off. Jump over the wall to avoid falling. Soon, the level will start moving up. Here, you'll find a set of Red Coins. Past them is the second Star Coin, under some donut lifts. Let them drop down to get it, then quickly wall jump back up. Next is a pyramid of donut lifts. Be careful about jumping up off screen, as Koopas are walking around here. The third Star Coin is a little to the left, so jump up to reach it carefully. The level will start moving to the right after the pyramid. Koopas are on some of the platforms, so be careful. There is an item block between the pipes if you need some extra health. Take the ferris wheel platform to the flag. The path to the castle will open up.
