So I've been prototyping games that if completed would be mobile apps most likely.
But, I'm developing them in XNA on the desktop because its the environment I like the most.
I know I could target windows phone and be testing the touch interface rapidly on that device but I don't own one and I imagine the build and deploy to the phone loop slows you down a bit.
Does anyone else prototype games that would eventually use a touch interface using mouse controls initially?
What tricks do you use to ensure that it will eventually translate well when you move to touch controls?
