I tried playing with my gamepad and the camera control was divided between the arrow pad and the right analog stick. I'm not sure if this is just because my pad is different or if you mixed up the axises or sommat, but it might be good to add a customization in there if possible. ^^
It was still playable, but the automatic following code for the camera isn't great and I gave up after a while. Overall pretty impressive though! fairly good platforming.
