An experimental Lucastarts game. Perfectly fine to a point, as your options are limited, and although a lot of times you need Fairy Tale Logic, the puzzles are all solvable.
What kills the game is the ending, where you face a limited try, limited time series of events, where the save&load system's problems become very very obvious. This still isn't much of a problem, as it is a Simon Says game, but on the highest difficulty you get no visual clues, so that's game over for anyone not being able to properly play a real instument (and no, not drum, dummy).
