This app is great. I played the first three stages and had a great time both playing the music game and making it through the story. The game is very much in line with other music/rhythm games, but since you play with a virtual keyboard on the iPad, it relates a bit more to a real piano than, say, a guitar hero guitar. The music is all from classics of Frederic Chopin, but remixed to match your modern adversaries as you make your way through the game. The art style is great and, once you are comfortable enough with a song, you can start paying attention to all the stuff that goes on in the background as the camera pans across the "stage" and the various characters. No need to be a piano player to enjoy this game. Im currently playing on normal and Im not having too much trouble making my way through. There are two difficulty levels above that, which I have not tried yet. Overall, great production value and good musical fun.
