Rules

• A blow lands on the nearest thing in its lane anywhere past the small tick on that lane, which marks your weapon’s reach. You don’t have to wait for things to arrive.
• Things take different numbers of blows. A stapler always falls to one. A monitor or a chair takes one blow of the katana, kama or yari and two kunai. A printer takes one katana blow, two of the kama or yari, three kunai. Diamonds over a thing show how many blows it still takes.
• The four weapons sit on a grid of reach and speed. The kama, a pair of sickles, is fast but reaches only things almost upon you, and every strike cuts with both. The katana has a middling reach and pace and hits hardest. The yari reaches furthest but recovers slowest. The kunai are thrown: long reach, the fastest hand, the lightest blow.
• Things are thrown from the far side of the room: they arc up out of view and come down the mouth of their lane, and red strokes at the lane’s mouth warn you just before. Monitors come down the high lanes, chairs roll in along the floor, staplers and printers come either way. A blow that doesn’t finish a thing knocks it back up its lane.
• A blow struck late, past the double tick near the end of the lane, is a perfect cut: it scores double.
• Each floor has a quota of things to cut down, 15 on the first and 3 more on each floor after. Then the floor’s boss appears in the window and throws everything at you. Before each throw it raises the thing towards the side it will come down, up for a high lane, down for a low one. A perfect cut sends a boss’s throw back at it; three on the first floor, one more on each floor after, up to six, bring it down for 25 points times the floor.
• Every department adds a thing of its own. In the mailroom, parcels burst into two envelopes. In IT, cables come down both lanes of a side at once, and both ends need cutting. In accounting, ledgers take exactly two blows with any weapon, and the first knocks them across to the other side. In the meeting rooms, an invite you don’t cut perfectly is rescheduled to the other side. In the kitchen, a mug you cut spills steam over the far half of its lane. In HR, reviews come back once, faster, for revisions. The executive floor sends all of it.
• Each department has its own boss. The Rubber Band Ball and the Franking Machine, which throws two at a time; the Blue Screen, whose throws stutter down their lanes; the Hanko Daimyō, who only takes a ledger sent back with its closing blow; Kaigi-bōzu, the meeting monk, who heals when a rescheduled invite is cut late; the Microwave, three throws at a time; the Reply-All Swarm, fast and in pairs; and the Shōgun of the 40th floor, who feints with his wind-up. The red marks at a lane’s mouth always tell the truth.
• With the boss down, choose one of three omamori, lucky charms, and take the stairs. Third Coffee recovers faster, Ergonomic Chair adds a fourth life, Second Monitor shows where each throw will land from the start, Paper Shredder softens printers, Casual Friday lengthens your reach, Out of Office absorbs the first hit on each floor, Overtime doubles how fast the multiplier climbs but makes a swing at nothing cost a life, and Team Lunch gives a life back.
• A stapler scores 1, a monitor or a chair 2, a printer 3. Every 12 things cut down in a row raises the multiplier by one, up to ×4. Being hit or striking at an empty lane resets it, and a blow at nothing also takes longer to recover from.
• Three hits and the run ends; your result is your score and the floor you reached. After each hit everything in the air drops and the next wave starts a moment later. Things fly faster and come closer together the more you cut down.
