A strange little side quest
Here is a rabbit hole for the next loading screen in Kage Samurai: Alexey Pajitnov created Tetris in 1984 after drawing inspiration from pentomino puzzles, then simplified the idea around shapes made from four squares. And then there is this: The word 'checkmate' is linked to the Persian expression 'shah mat', used when the king was trapped. That is the kind of background detail that makes another attempt at Kage Samurai feel a bit more connected to the history of play.
