It has outstanding game play and great graphics for a Game Boy Advance Game.
The graphics and music is really spot on. The music is pretty catchy, and it fits perfectly with the game. It may sound a little bit kiddish to you, but Mario themed music was always a little bit on the childish side, so get used to it. You also may find it humorous that Mario and Luigi don't speak English this time around. Instead, they speak in gibberish which is like how the Sims characters talk. The graphics are also amazing. Everything looks smooth, bright colorful, and the outlines are also smooth. Everything looks up to par with Game Boy Advance Graphics. Also, there's a lot of detail in the foreground and background to give it three dimensional effects. This game is not too easy or too hard. There are a lot of hidden challenges and items to find, but the controls are simple enough for everyone. The difficulty level is just about right for the most part.
Presentation - 10 It has a hilarious/strong story, and core challenges of the game prevent if from becoming too easy or hard.
Graphics - 10 They are generally up to par with GBA graphics, and the frame rate is smooth.
Sound - 8 Although the music sounds childish, it still sounds epic at some areas of the game. It may be strange listening to Mario and Luigi speak gibberish sometimes.

Lasting Approval - 8 This game will take you a long time to complete, but the replay value is somewhat limited.
Overall 9.2 out of 10 Game spot score 9.0 out of 10
