Track generation needs a slightly longer bit at the start that is straight, wide and has no obstacles.

The reason for this is the way the touchscreen controls work (exclusively played on phone with touchscreen). They are surprising to at least me, but possibly to a lot of people who have played mobile games. I was expecting it to be like a virtual joystick - wherever you put your finger down is the reference and then you are steering relative to that. The problem I'm having is that it's really hard to put my finger down at the start of the run and not have an immediate swerve of the ball. When you're on narrow track (or effectively narrow track due to an obstacle) like today a large proportion of the time I immediately died before I was in control of my ball.

AFTER that the controls work well and I really like them. They give more precision than a "virtual joystick" would. But I think they need explaining ("ball goes towards finger") and allowance to get in control at the start.
