Using the Whip
Not only can the Whip get far items, but it can also move some heavy cubes and perform a swinging move. Hold [B] while in the air, and when it grapples onto something, press [Left] or [Right] to swing. Release [B] to let go the Whip.

Easy lives
Keep returning to The Desert Ambush to gain more 1-ups.
Go to the Ice Temple multiple time to get the lives there.
Go to the Polar Freeze zone. On the second ice blocks, dash until you get to the fourth block and grab the extra life. Note: Defeat the Boss and escape repeatedly to get a lot of lives.
Combo
Equip Ultimate Form, then use Buster Shot. Keep pressing [Down/Forward] + [B] (for Buster attack). Anything in front of you will be obliterated.
Equip all the EX-Skills. Dash and Z-Saber, then hold [Up] and Z-Saber, and hold [Down] and press Z-Saber.
To Equip Chain Rod as [R] and Z-Saber as [B], hold [B] + [R] until they fully charge. Then, release [B] then [R]. Note: This is a close range attack.
Forest Of Dysis: Rare elf
The rare elf "Zero" is found in Forest Of Dysis (the stage with the forest) when in easy mode. Once you are in the inside part of the stage where you fight the statue that raises water and throws purple beams, destroy the statue. Afterwards, jump the pit and slide on the left side wall through a secret passage. Keep sliding down and on the way you should find the rare elf. If you keep sliding down, you will reach a secret area with lots of crystals and an extra life.
Crystal Caves: Secret area
When you start, go up the hill and destroy two robots. Then, go down but watch out for the spikes at the bottom of the hill. Start going up the second hill. Jump on the ledge but do not jump over the ledge. Instead, slide down the wall on the right in the pit and keep holding it. You should go into a secret area that has a cyber-elf capsule and a life. Note: When you get out, you will need the light-blue armor. If you do not have it, you will fall into the spikes.
Sand Wilderness: Extra life
First, talk to the Operator and transfer yourself to Sand Wilderness (the first area that you are in). There is an extra life hidden there. It is after the second mini-Boss, after the bird in its nest next to a gunman, but before the two birds in one nest. You will find it when you are there; it should be in an opening under the gunman.
Defeating Bosses
For easy wins against most Bosses, charge the Z-Saber and attack the Boss. Keep hitting him and, with five or six hits, he will be destroyed.

Glitch: Moving Zero
Stand on the Transerver just enough to talk to the commander. When it turns back to Zero, he will be in the middle.
Glitch: Misspelling
When you defeat every Boss, X will appear and start talking about the Dark Elf. He explains that he is trying to keep her asleep and says "With my remaining power, I'm still TYING NOT WAKE her up...," instead of "With my remaining power, I'm still TRYING NOT TO wake her up..."
After defeating the four bosses on the monitors, there is a scene where Elpizo tells the members of the resistance to fire at Neo Arcadia. Ciel comes in with the Scientist and tells Elpizo to give them time (or something similar). Before Elpizo teleports, he says "Don't worry. We can work this OUR later", instead of "We can work this OUT later."
