This sounds awesome. I've never played the official games, but I would be willing to pick up a bongo controller to try this.
As awesome as the origional games are... you are limited to the included songs, which ive way over played
As clunky as the controller is it is amazingly fun and I think its simplicity lends itself to people's willingness to try it out.
Controlls are left drum, right drum, both drums and clap. The claping is a great game mechanic.
Its 1am here now but i cant sleep because my head is full of new game modes, layouts, designs mechanics and other ideas I want to design. Im going to burn through a few sketch books on this project >_<
