Level 3-4 (Mario vs. Donkey Kong)
In the first area, the player can progress in one of two ways:
Once at the blue Color Switch between the two Kurasshās, the player must jump up the blue platforms and move left to find the Key. Then the player has to press the red Color Switch nearby and drop back down to the red bridge below. After crossing the red bridge, the player has to avoid the Kurasshā and ride the moving platform to the other side, and then jump up the red platforms to reach the locked door above.
In the second area, the player needs to ride a Kurasshā up to reach the next platform. The player then has to climb up ropes while avoiding the fire from a Katakata Kaen Heihō and then jump over a pair of spikes at the top. Next are some Ninjis the player has to jump across, followed by some Katakata Kaen Heihōs and ropes that will lead to a 1-Up Mushroom and the Mini-Mario.
