What is TSUKI: Nine Lives?
TSUKI: Nine Lives is a 2D action platformer in the classic run-and-jump tradition, built for the browser and playable on a phone. You play Tsuki — tsuki (月) is Japanese for moon — a black cat with red eyes and a crescent moon on her brow, and you run, double-jump, dash and dive-stomp your way through seven worlds of increasingly hostile terrain.
Every cat is said to carry nine lives. In this story the moon is where those lives come from — and something is draining it. A shadow called Kage is taking the moonlight one land at a time, and with every land that goes dark, cats everywhere lose a life. Tsuki follows the moon across seven worlds to take the light back.
The chase ends underground against Orochi, the serpent that swallows the moon. Almost every culture explains an eclipse the same way — something eats the light and the light has to be won back. This game takes that literally.
There is nothing to install, no account to make, and no wallet required. It runs in the browser tab you already have open, and it is free forever.
The lore
Tsuki · 月
Tsuki (月) is simply the Japanese word for moon. It is the name of the cat you play, and of the community she came from.
Cats have belonged to the moon for as long as people have written down either one. They wake at dusk, their eyes open and close like a phase, and they keep coming back from things that should have finished them. In Japan a black cat is good luck — a ward against misfortune, the opposite of the Western superstition.
And when the moon vanishes, the stories agree with each other more than they should. A Hindu tradition says Rahu swallowed it. A Norse one blames the wolf Háti. Japan has Yamata-no-Orochi, the eight-headed serpent. Every version ends the same way: the light is taken, and then it is won back.
That is this game. A shadow called Kage is draining the moonlight one land at a time, and every land that goes dark costs cats a life. Tsuki follows the moon across seven worlds to take it back, down to where Orochi waits.
