I want to make a game that depends on the phone orientation (changing shoot direction with tilt), however I need to test this on PC. So is there any tool I can use to simulate the orientation of the phone with mouse or keyboard of my PC? Something like joysticks on the screen.

Thanks for any help!

Edit :

Thanks to @jhocking for his suggestion of Unity Remote. I, however still can accept a solution with using only PC, since I'm afraid of shortening my phone's battery life, for some reason.
