Crimson Blade is a side-scrolling samurai action game about a lone ronin cutting a cursed province clean.

Run, jump and dash with a blade that means it. Chain a three-hit katana combo, turn your dash into a strike, and open enemies up in the air. Every connect stops time for a beat, shakes the screen, and leaves a brush-stroke arc hanging in the air. Honor marks every demon you cut down; crimson spirit orbs stitch you back together.

Across three acts — the misty Bamboo Path, a village burning at dusk, and the storm-lit Demon Bridge — you'll face ashigaru swordsmen, patient archers, club-wielding oni brutes, and hopping gel slimes in molten orange and blue that spit wobbling globs and burst when they land. At the far end of the bridge waits the Oni Warlord: he charges, he crushes, and when his armor cracks he rages — and the bridge itself shakes slimes loose.

• Full move set: run, jump, dash (with brief invulnerability), 3-hit combo, dash strike, aerial slash
• Four enemy types plus the slime, all hand-tuned to fight differently
• A two-phase warlord boss with charges, ground slams and shockwaves
• Health, honor scoring, pickups, pause, defeat and victory screens
• A hand-painted ink-wash world with torii gates, parallax mountains and drifting petals
