but why?

Because couch gaming, because lazy ;)
And because 40" and 5.1 speakers.

Wireless mouse no longer works on coach?

Gamepad with touch pad would do well too i believe.

Wireless mouse works but not to well.
Controller is still more comfortable. Unfortunately i don´t own a Controller with touch pad.

Anyway, it´s no biggie. Just wanted to know if anyone can confirm or deny on controller support.

In worst case i think there are programs to emulate mouse using gamepad. Assuming the game does not require any reflex-critical moments like GWBW.

The game doesn't support gamepad, I'm sorry >_<

I just finished the game playing with a Xbox 360 controller with the mouse mapped to one of the analog sticks. The game is playable, however I can see how the mini games require precision that would be much easier with a mouse. I did have to tweak the mouse sensitivity because if it is too low, the shaker will not be able to mix.

Just finished the game with the steam controller. smooth. no problems with the touch pad.

Sucks =(
