Floor 1 of the climb: Masayoshi in indigo squared up against a Grey Yakuza on a dark neon back-street, the enemy plate reading GREY YAKUZA at 29 of 29 health with an attack-7 intent above it, and a hand of three Katana Slash and two Guard cards fanned over the END TURN bar.

What it is

A turn-based roguelite deckbuilder. Masayoshi steps out of Crossfire and starts climbing the Cybertower toward the Wound, the tear at the top that is pulling time apart — nine floors of Act 1, then the Black Oni waiting on the roof. The map runs four lanes with crossing links, and every fight node names its faction before you commit: yakuza, ninja, drone deck or hellgate, each with its own card pool, so the route you pick is the deck you finish with. Shops, rests, events, treasure and elites sit between the fights. Thirty-five cards across Blade, Gun, Spirit and Tech, a Spirit meter that specials spend, ammo on the gun cards, and Burn, Exposed, Weak and Blind to stack. Act 1 is what plays today; Acts 2 and 3 come later. It runs the whole way through on a phone.

The mechanic

The Rewind

Lose a fight and a run is normally finished. Instead time stops in a black-and-white ink flash and the game offers the fight back. The whole run state was snapshotted the moment the fight began, so the replay returns your deck, HP, gold, relics and the enemy group at full health, minus one charge, and starts again at turn one. The enemies run the same intents, but your draw pile is reshuffled, so you do not get handed the hand that lost. You start a run with one charge and can hold three — earned off the act boss, a shop Time Shard, or the Echo of Hideo event. One Rewind per fight, even holding three. Lose the replay and the run really is over.

In the wild
The Act 1 map: a four-lane board nine floors tall, the four floor-1 fight nodes outlined in amber along the bottom, ramen bowls for rests, a yen shop and a treasure chest on the left lane, an event node marked with a question mark, and the Black Oni's 鬼 banner across the top, under a line saying fight nodes show the faction you will meet and the faction decides which cards you can win.
The map — four lanes, nine floors, the Black Oni on top
Floor 10, the boss: Masayoshi facing a pale-robed oni with a long blade in front of the tower's rain-streaked gear wall, the plate reading BLACK ONI at 111 of 111 health with an attack-14 intent, a Time Shard — +1 Rewind toast below it, and a hand of two Katana Slash, a Pistol Shot, a Guard and a looted Hellfire Ball.
Floor 10 — the Black Oni, 111 HP, attack 14
The Rewind prompt: the whole fight drained to black and white behind a white dialog headed TIME STOPS, telling you Masayoshi is on the floor and the ink runs backwards and you may replay this fight from its first turn — once, with Rewind charges: 1 and two buttons, REWIND (1 LEFT) and ACCEPT DEFEAT.
Time stops — replay the fight, or accept defeat
On a phone
Floor 1 on a phone held upright: the 3D stage across the top with Masayoshi facing a Grey Yakuza on a neon street, the enemy plate at 29 of 29 health, a stats strip reading HP 70, Block 0, SP 0, one Rewind charge and 3 of 3 energy, and five cards — three Katana Slash and two Guard — fanned along the bottom.

A two-on-one fight on a phone held upright: Masayoshi against two Red Yakuza caught mid-swing, both plates reading RED YAKUZA with an attack-11 intent at 25 of 37 and 31 of 31 health, energy spent at 0 of 3 so the two cards left in hand sit greyed out, and the full-width END TURN bar beneath them.
