Use Levitation without having it equipped
Have three Psi powers equipped, none of them being Levitation. Then, double-jump, hold L1 to glide, then press X while gliding to grab the Levitation Ball. This will work just as if you are using it normally. Note: You must have completed “Milla’s Dance Party” in order for this trick to work.
Claw TK attack

Hidden figments in Edgar Tegley’s mind
While in Edgar Tegley’s mind (with the dogs and bull), there are two figments that are difficult to find. They are not normally present, and you must unlock a way to find them. Take the window painting with you and place it where the guitar is located. It will no longer teleport you, but instead reveal a figment. Do the same thing at the location where you would place the vines to find the other hidden figment.
Easily complete “Black Velvetopia” level
When you are looking for the cards, defeat the wrestlers and obtain the cards (in any order). Once you have three of the cards, make sure you have your Levitation power maxed out by ranking up. Once you have the high jump levitation, go up to the top of the card tower where Edgar is located. Walk into the cards Edgar is working on so that they fly away. Then, activate your levitation power and go to the edge of the stable cards, then jump. You should activate the final Boss fight of El’Odio, and complete the level. This will save about fifteen minutes of running and jumping in the level.
Defeating Jasper
To defeat Jasper in Gloria’s theater, use Pyrokinesis, Levitation, and whatever else desired. Use the Levitation Ball to float up the top where the lights are located. Jump and use the Levitation Float above the music note to get there. Use Pyrokinesis to light the candles and make Jasper dizzy. Go down and punch him until he is no longer dizzy. Repeat this to defeat him.
Defeating the Lungfish
To defeat the Lungfish in the first and second stages, whenever he blows out the yellow boxes, hit the one he starts to suck in. When in the final stage, stand by a clam. When he starts swinging the thing on his head, punch the clam shell, then punch him.
To defeat the Boss in Lungfishopolis, whenever he shoots the beam thing at you, activate the shield to make it go back at him.
