Drive two mirrored snakes with a single set of controls and keep both alive as the speed climbs.
A single input commands two snakes at once. Left and right are mirrored between them while up and down are shared, so every turn you make pulls them in opposite horizontal directions. Feed each snake its own food to grow, and survive as long as you can.
The body that grows and the tail you must not hit are Snake, the form that spread through 1970s arcades and then onto every Nokia phone of the late nineties.
The original twist is that there are two snakes, mirrored, sharing one set of controls. Every input steers both, in opposite directions.
That converts a game of route-planning into one of simultaneous constraint. A turn that saves one snake condemns the other, so the only survivable paths are the ones that work for both at once — and they become scarcer as both bodies lengthen.
