Become a master of the drums! Play through 15 levels, including both training and song levels. With 10 songs, it'll be enough to keep you occupied.
But if that's not enough, there is also an achievements system in place for those who want an extra challenge! 18 achievements to collect, can you get them all? Getting achievements also unlocks new levels!
All the songs can also be downloaded from the NG Audio portal and the song links are provided ingame. If you ever get hooked to one, you can always download it and listen to it as much as you like.
