It doesn't really work with a mouse...
I've recently got EBA and I really enjoy it. But this game just doesn't really work because using a mouse isn't as fluid and precise as a touch screen and stylus. I found it very difficult to match the cursor with the beats in time and the bars were sometimes too long, especially at the end of the first song. Which brings me to my next point: the choice of songs wasn't great. Maybe if you included some famous songs that weren't in EBA the first time around, it would have improved the game. Who knows? Maybe this game plays better on a tablet PC, but with a mouse? No. Sorry, dude.
