Either I'm out of practice...
Or this is hard! In a good way though!
This is very much an improved game. It feels very polished...and you even added in several features...such as the keyboard/guitar style controles ^_^
The game is very rewarding with the award points as well. While not exactly new in comparison to your previous game, the number and variety of guitars to unlock is very cool. The descriptions of the guitars are half the fun too!
As I mentioned earlier, this game brings about a whole lot more challenge (for me, anyway). I was having an easy time with it at first until I came to "Trainwreck." The name said it all for me. I then knew what I was in for (it was a song only half-way down the list after all!). In addition...getting perfect awards with songs of those lengths?! O_o
One nitpick: the announcers for both this and the previous games are awesome...but this one lacks a comparative "umph." After listening to the last announcer for a while, this one seems a little half-hearted. I kept on thinking, "you don't seem too excited." As a side note, I thought it was funny when I am on a roll and screw up royally, so the announcer says something like, "Supe-WEAK!" >_>
I do miss some old titles, by the way. I know that you shouldn't repeat songs, but I missed Guitar vs. Piano. Plus some Mario/Zelda songs just because I'm a gaming geek ^_^
Once more: this is an improvement to an already awesome game. I'm not even really into this brand of music either. It keeps me entertained and challeged (very much so). You, sir, deserve a hearty pat on the back, and a whole lotta good votes and reviews. Awesome job.
