You have completed all the Challenges! Funky Student would be proud.

This is probably the second hardest achievement in the game to get, you have to complete all of each characters challenges. Everyone always has a character that doesnt quite work out for them so this is going to be challenging even for those who are good at these kind of modes.

Overall, challenge mode starts off easy, you are given very short combos at the start, anyone should be able to do these no problem, then it gives you a few basic combos to do, still very easy at this point, then it gets onto giving you the longer combos. It is best to take these combos in parts and then doing the whole thing once you have all the parts learned. You can also see a demonstration on what way is easiest to do the combo and dont worry about using walls, if you think the combo is easier against a wall, then go for it.
