Crossy Road took 92 lines of code. Those lines got me grass, trees, pavement, cars from left and right, controls and death when hit by a car. Agar.io took 63 lines of code and includes regenerating "dots" for eating, 20 dumb bots, controls, growing when eating and respawn when eaten.
(Btw: the new builtin game video recording feature of Windows 10 on Windows+G works great!)
