Shape Shifting is a race where the vehicle is the decision: the track changes terrain constantly, and you switch to whichever vehicle handles what's ahead — a wheeled one on road, something else on water or rough ground.
Getting it right is faster than any driving skill, which makes it a reading-ahead game rather than a reflex one.
One button cycles vehicles. Each is fast on its own terrain and slow on everything else, so the timing of the switch is the whole game.
Yes — a simple one-button racing game with no violence.
Yes — tap to change vehicle. Nothing to install.
