Atmosphere
The atmosphere in this game is nothing special. It's bland at best. The plain red background, the repeating textures, and the 20 second 8-bit loop in the background are very boring. For atmosphere, Saving Mozart gets a 3/10.
Originality
Saving Mozart is a simple platformer, with only two colors. Red and white. It it's not very original, so it gets a 1/10.
Execution
The game is very poorly executed. It's a boring 2D platformer, with a boring color palet, boring gameplay, and a boring 8-bit loop in the background. It's just... boring... 1/10.
Story
There is in fact a story, but it's not very interesting. Guys dog dies, guy is sad, guy tries to bring dog back to life. For story, I give it a 3/10.
