You ruined it. I really don't like the changes. The gradient-based art looks like shit, and the way wrong notes distort are not only annoying, but kill the song and make it impossible to jump back in. The music was nothing special either. To me, this seemed more like a bad fan tribute than a sequel. I'm disappointed.
This was little sloppy. The gameplay was fine and you really had the right idea going, but you just didn't quite put it all together. There were way too many glitches, slightly substandard graphics, and things got very cluttered and hard to use with an overpacked inventory and unmanagable skill points and armies.
The defence levels are kind of crazy, and the classic ones are just plain awesome. I like both the graphical improvements and new features, but the gameplay and maps in 2Play were a bit better for me. I'd like to see a boxhead were you can progress through levels with a plot, etc. similar to the Haloween one you initially put out.
