Well the game got Hardest Action 1000 in the 07/08 achievement awards on this site if that means anything.
To get 1k you need lots of patience (to get around a few of the game issues), you probably need to like the game to some extent, :P and will require a lot of skill/memorisation for getting S ranks and finishing some of the hard mode levels. Then there's just ever so time consuming medal collecting.
Fun game imo and I enjoyed getting the achievements but I realise it's not for everyone.
Im a solo musician trying to be heard in the world, take a listen to my Rock/Post Grunge style songs, you might find something you like, add me and thanks for your support:
