Mad Maestro! is nothing extraordinary from this point of view. The style chosen is once again a cartoonish one. Graphics elements are nice and suitable for the game, but not great. I'd say they're quite simple, and especially the audience listening to your performance in some stages is awfully plain. Probably this is not a terrible issue, considering that characters and environments are secondary if compared to the music experience. Despite this fact, the animations of some stages are odd and funny and they add an original touch to the game. Depending on how your conduction is going, you'll see strange episodes or bizarre actions happening on the background. For example when conducting in a very bad way, you will see disasters of all genres happening at the same time! Sometimes you'll be also distracted by the absurdity of it all (like it happened to me in front of circus bears trying to kill penguins!). In general the atmosphere of the game is hilarious and pleasant, also thanks to this addictional fun.
For obvious reasons music the most important element of the game. The choice of including only classic pieces in a videogame is kinda original and unusual. Let's hope this idea works also with players not interested in this genre. In fact, we have other music games based on the most various music genres (from rap to rock and from J-pop to hip-hop) because those are the genres that the average player usually prefers. But regarding classics, it seems they are considered as old music not able to interest common people. From a certain point of view, the idea of Mad Maestro! surely is incredibly "alternative", even if we cannot consider classical music alternative only because it's not much well-known among some people. The pieces included in the list are some of the most famous of the history of music (part of the "9th Symphony" by Ludwig Van Beethoven or the "William Tell Overture" by Gioacchino Rossini) while some others are not very famous among a larger audience (for example the "Ballet of Unhatched Chicks" or "Baba Yaga's Hut" by Modeste Mussorgsky).
Apart from the Music Room Mode, the execution of the piece depends on the conduction of the player. So, if you're a connoisseur of classic music and you cannot believe the terrible sound coming from the game is your beloved "Flight of the Valkyries", that is 80% because your conduction sucks. The other 20% is probably because you don't like classic pieces to be synthetized. This can be, I'm not questioning the possibility, but hey, don't forget Mad Maestro! is only a videogame, not a real performance from the London Philarmonic Orchestra!
The game presents a wide choice of classic pieces and it's not as simple as other music games. At the beginning some stages will be difficult to be cleared, because of the difficulties of the music pieces. Especially trying to satisfy all the fundamental requirements for a good performance won't be so easy for beginners, and maybe also for the ones who know the music. Not saying that Mad Maestro! is a very long game, but this is only a music game, not adventure or role play, so lenght is proportional to the genre. To avoid repetitiveness choosing a decent lenght is not a bad idea.
