A strange little side quest
Here is a rabbit hole for the next loading screen in 2048: X2 Legend: Alexey Pajitnov created Tetris in 1984 after drawing inspiration from pentomino puzzles, then simplified the idea around shapes made from four squares. Another piece of context lands nicely beside it: Nintendo's Donkey Kong arrived in 1981 and introduced the character first known as Jumpman, who later became Mario. That gives 2048: X2 Legend a little more company than it first appears to have.
