TRAILBLADE
No weapon. Your speed is the blade

Midnight in a gothic city. Lost souls drift through the streets, and if they are not home by dawn they fade forever. Only the Night Courier can carry them, and the imps want them too. That courier is you.
You carry no sword. Every dash leaves a trail of afterimages, and the trail cuts. Graze past a monster without touching it and the trail takes it down. The faster you run, the sharper it gets.
- TAP anywhere to dash there. Tap farther away to dash harder.
- Your afterimage trail is your blade: BLUE › YELLOW › ORANGE › RED. Faster means wider and stronger.
- HOLD to slow time and aim, then RELEASE to dash.
- Only your afterimage kills, and touching a monster costs a heart. Skim past them as close as you dare and let your trail do the cutting.
- RED means danger. Red circles and red lines are attacks about to land. Dash out of them.
- Stone gargoyles only crack at ORANGE speed or faster.
- The DAWN clock never stops. Get through all 8 stages of the night before sunrise.
Made for phones in portrait (one thumb), and it plays just as well with a mouse. A short picture tutorial shows you everything as you go.
- Stone pillars crash down from the sky and get in the way of your dash. You bounce off them, and they also block enemy fire.
- Golems shove the pillars into the middle of the street.
- Gargoyle statues on the walls spit fire across the road. Their eyes glow and a red line shows where the shot will go.
- The Headless Knight smashes through pillars, and the Raven King's landing crumbles them.
- Speed is your weapon: your blade is only as strong as you are fast.
- Slow time: hold to freeze the moment, aim, release.
- Beat the clock: the sun is rising, and every second you save raises your rank.
Between stages you stop to rest and repack your courier bag.
- Buy goods and drag them into the pack. Every item has a shape, so space matters.
- Drop an item on its twin to merge it into a higher tier (I → V).
- Bottled Souls become ghosts that run with you and replay your dash a moment later. Their trails cut too.
- Keep your CHAIN alive: every 6 kills, another soul joins your parade of ghosts.
Swift Boot, Sabre, Ghost Lantern, Brass Bell, Pocket Watch, Powder Keg, Locket and Sealed Letter tune your dash power, blade width, trail length, cooldown, slow time, dash blasts, hearts and coins.
- The Headless Knight: watch for his red line, then get out of the way before he charges.
- The Raven King: he marks a red circle where you stand, glows red, and dives at it along a red line, landing with a shockwave. Get out of his path and out of the circle.
Finish with hearts to spare and time on the clock for a higher rank (S / A / B / C).
