Quoted from TinyBlackDog:The song modes in rush have been referred to as “planet” modes in several places - they do look like planets on the lower half of the playfield, with Cygnus X1 Books 1 & 2 being more obvious (with the rings). 2112 in the center is very “sun” like. I suspect this will be somehow representing progress towards the wizard modes.
Ok get it now, I think. But I do see what you are referring to on the playfield. Hopefully they improve the graphics a bit on that screen.
