How to Play Mario vs. Donkey Kong
Quick start
Open the first world with "GAME" and enter 1-1. In the first half, use the color switch to change the scaffolding, use B to pick up the key, and bring it to the door with the keyhole before the return time runs out. In the second half, aim for the Mini Mario capsule. If you can get them safely, you can try the bonus by collecting three presents, but prioritize the key and the exit first.
Controls
D-Pad: Move, operate on ladders, ropes/wires. A: Jump, get off the rope/wire. B: Holding/throwing something, letting go. Enter free scrolling with L or R and check the stage with the D-pad. Pause with START. Down + A to do a handstand, mid-handstand A to high jump, while running + A in the opposite direction to do a backflip, and Up + B to throw something held upwards.
