Yes, a controller is supported, although neither the game nor the store page tell you so. There's no bindings listed either, but I had no major problems after figuring out the keys.

Worth noting, game was also played using only a throttle ;P

i could not get the controller to work...hmm

:v

okey the camera is constantly moving although i'm not touching the right joystick :/ any hints? thanks

My controller is also not working
