Don Doko Don Cheats

In round 1, jump and swing on the top ledge to find a shimmering circle. Keep hitting it until a key appears, then go in the door (kill the mushrooms in your way but don't finish the round). In the hidden room, find another key in the top left corner (but try not to die getting there), and go in the next door to enter the password by breaking the jars.

There are 5 hidden rounds in Don Doko Don. They are found by swinging at certain spots to reveal a key (this spot will shimmer as you hit it). When you defeat all the enemies in a hidden room, a chest will fall that you can hit to open. Be sure to grab the crystal ball. If you have all 4 crystal balls after beating the last hidden room, you'll learn the password to access the Reverse Rounds. Beating a hidden room also lets you skip several rounds, a fast way to finish the normal game.
