I like Bit. Trip Presents: Runner 2 Future Legend of Rhythm Alien. It's actually one of the few games released onto this year's PlayStation Plus Instant Game Collection that I was looking forward to playing.
While the game is musically-inclined I'm not so much a fan of the music in the game. However, the better part about the game I think is the gameplay itself. It's a platformer that has you thinking on your feet quickly by combining all these offensive and defensive elements to the character. Ducking, blocking, jumping, and ninja-kicking down walls all come into play.
It's been awhile since I last played the game, but I did manage to unlock about half of the game's trophies (including the one for having three different triple perfects on each area, I do believe). Some of the levels I can't figure out how to unlock though, that being the treasure rooms or whatever they were called. You need a key to get past locks, and that is something the game doesn't go into great detail explaining.
