Autoscroll controller

[PIXELATOR37]

Once the player gets a safe distance from the screen edges, and has this controller's location on the screen, the screen will center on the controller, and will start to autoscroll through its nodes at a configurable rate (in pixels per second). It should have a parameter that, if ticked, makes spikes pop out from the edges of the screen most perpendicular to the scroll direction (meaning, on the top and bottom for vertical scroll, and on the left and right for horizontal scroll) when you get near those edges; see The Tower in VVVVVV for an example of what I'm talking about
