Well I thought that I was happy with the controls but as soon as I added a virtual camera things started going wrong. At first the player ran towards the end of the level. I soon realised that the answer was to subtract the position of the camera from the touch positions but then I had the problem that you had to kind of scroll upwards with your finger all the time....
I finally added a trigger to move slowly forward if your finger is above a certain distance thus avoiding the scrolling with your finger. I'm still not 100% happy but I'll move on with other features and try to revisit this.
