Man, this is really one of those "you love'em or you hate'em games"
personally i find this game mind bogglingly* boring, but I give it a 5 because I see why people may like it.
Simply enough your a cartoon dog thing and have different "apprentices" that sing... The songs actually have a pretty cool beat to them and a neat rythm...
The graphics are like paper cut outs (i refer to southpark or paper mario if you've played it) and can only be visually pleasing for so long.
The gameplay is this (back on track), the apprentice gives you a series of buttons you must hit in a certain order (simon says) and you need to hit them, the more you get right the more buttons he gives you until you either lose or complete the level.
The gameplay is ok for the first time you play the game but wears very thin shortly afterwards, definently a rental
