Reviewing thyself.
I must say that when I first saw the introduction where the artwork came together in the background, I nearly shed a tear. I really thought from the menu ALONE that it was going to be a great game. I didn't know what to expect.
Then I saw the puzzle game. It took me roughly a minute to figure out what to do - no trouble at all. Then my mind began to ramble on and on about all the possibilities and solutions. THAT is exactly what a puzzle game is supposed to do. Let you think about it for a little bit until you piece it together in your head.
I was debating if another song should have been added, but I never came to a conclusion. Honestly, I got stuck on level 19. Another 10 minutes and I probably had it, but I didn't want to spend too much more time. Makes my head hurt when I spend way too much time trying to figure it all out in one setting. Maybe I'll come back to it later. I'm so glad you included the save system =) .
I never actually played the first one, but I definitely enjoyed this crazy new game in which I could not find one game to compare to. I loved it --- 45minutes for the first 18 levels if you really wanted to know.
