Can I use an USB Game Controller to play PPD?

Well, I have a problem with my keyboard so I'd like to play with an USB Game Controller. Can I use it? And which broad?

By USB Controller, you mean a normal PC controller ?
I have one as well and it works just fine. :) If you want to play 2 handed, you might consider getting the CSInput Mod in the Mod section which allows you to use the DPAD. :)

Current versions of PPD already come with CSInput

Right, my bad, I keep forgetting since I had to get it manually. .-.
