I haven't rated this game, but i played it too see and what i notice is that the sounds/music is not something a Nokia 3310 will make.
Listen for an example to the ringtones in this video: https://www.youtube.com/watch?v=TOc84Z-y8g8
The screen is done nicely, but if you compare this to what a Nokia 3310 screen looks like, it is differently. The pixel effect you make looks nice, but that is not how the 3310 screen displays pixels.
The art however is nice, but that does not count for the restrictions of a Nokia 3310.
