Dance Paradise

Unfortunately, this requires playing every song and beating the challenge that goes along with it on Hard mode. You can't just unlock the last set and beat the last song and be on your merry way.

The good news is this isn't that hard at all, as long as you have the energy to go through all (49?) songs. Hard mode is not that much harder than Easy mode; the moves seem to go a bit faster is all. You can hit most of them without too much effort. I got Star rank on nearly every song in the Hard career mode just by half-assing every song.

The hardest part of this will be the song Dance Dance. They will throw a ton of tricks at you (or whatever they're called), which wouldn't be too bad, but the moves seem somehow harder to hit on this song than they are on most songs. Instead of keeping the vitality guage at 90% or higher on this song, like I did on most songs, I had it drop to about 75% once or twice... Close call, there, huh?

This game was obviously designed for a younger audience, so even this achievement shouldn't be too much trouble.
