Ranked in these QuestionsQuestion Ranking
Pro Supports most common music filetypes
Overall the game supports most musical filetypes such as MP3, OGG, WAV, FLAC, WMA (Windows only), AIFF, WV. This means that most peoples musical libraries will be ale to be used in the game, which is convenient.
Pro Classic vertical shooter
Much like classic arcade shooters Symphony plays as a vertical shooter where the goal is to shoot enemies on the board in order to collect powerups and progress. So for those that are fans of this style of game they should enjoy it, much like Space Invaders, but using ones own music.
Con Costs extra money (DLC) to use iTunes music
M4A and AAC are available to be used in the game only through DLC that costs money. While a nice way to get the price down on the game for those that don't use those file formats for their music it may be a pain to have to pay extra for those who's library consists of mainly iTunes music.
Con Does not differentiate levels as much as it could
The levels are supposed to be reactive to the music being played but more often than not the levels just feel randomly generated and do not show much in the way of being driven by the chosen music.
