Legend of Kay is an action-adventure game where a young hero called Kay, a cat, rises to the challenge when emperor Shun, king of the mighty gorillas, invades the island Yenching with his troops. Kay may only be a scholar, but he is a brave and agile fighter. He leaves his village only with his sword and soon becomes a seasoned fighter.
The gameplay in Legend of Kay is reminiscent of eastern martial-arts-movies. There are various moves the player can execute: uppercuts, back flips, somersaults, powerful magic attacks, and combo moves. When you gain a combo, you can auto-aim at enemies, which makes it easy for the player to execute double and triple blows. In the beginning, there is only a sword, but later in the game, Kay receives steel claws and a powerful war hammer. All weapons can be upgraded. Kay has to fight a lot of different enemies on the ground and in the air. There is a lot of jump-and-run action, puzzles, and many fights.
