I have not much to say about LOUD on Planet X, it wasn't a game I enjoyed at all, so I didn't play it more than what I felt was necessary to get a grasp on it. It is a music-based tower-defense game where you tap to the beat of the music to attack aliens, using special items and more powerful moves when appropriate. The main issue I had with it is that I disliked every single track of music they had, which is really bad for a music-based game. So that really soured me to the whole thing. I also was a bit confused about the timing of taps, sometimes it followed beats, sometimes I felt like I was just tapping willy-nilly, still hitting the mark. Maybe this game will be more suited to your musical tastes, but it sure wasn't to mine.
