End of the Hour Glass

A strange little side quest

Here is a rabbit hole for the next loading screen in End of the Hour Glass: The name Tetris combines a reference to four-square pieces with Pajitnov's interest in tennis. The surprising part is how quickly the next milestone followed. Nintendo's Donkey Kong arrived in 1981 and introduced the character first known as Jumpman, who later became Mario. That history is one reason familiar mechanics can still feel new when they are recombined well.
