Delta-V: Trajectory
Trajectory puzzle. Survive.
Free · Designed for iPad. Not verified for macOS.
A one-finger gravity puzzle through ten star systems. Aim, launch, slingshot — momentum and physics do the rest. Synthwave-noir arcade in pure vector neon.
Pilot through ten star systems on a single trajectory. Aim, launch, slingshot — gravity does the rest.
Delta-V is a one-finger arcade puzzle. Pull back from your launch pad to aim and set power, release to launch. Then ride momentum through dense star systems — bend your path around planets, slingshot off moons, scan exotic gravity wells, and dock at the next port before your fuel runs dry.
Every system tells a story. Every system raises the stakes.
ONE-FINGER FLIGHT
• Tap and drag from the ship to aim and set power
• A live trajectory preview shows the gravity-bent path before you commit
• Mid-flight: tap anywhere to fire navigation thrusters perpendicular to your heading
• Toggle between system overview and ship-follow camera mid-flight
TEN STAR SYSTEMS, ONE STORY
A handcrafted arc from HIKARU RELAY to THE BEACON. Each system is procedurally seeded but story-narrated — broken comms relays, pirate sieges, derelict mining stations, a black-hole gauntlet, a final stand at the edge of charted space.
DYNAMIC OBJECTIVES
Every system asks something different: salvage cache fragments, gravity-scan a target planet, slingshot off a named world, bump a specific moon, earn credits the hard way, or finish a leg without spending a single thruster correction. Bonus credits stack up.
UPGRADE YOUR SHIP
Spend earned credits at any starport's shop. Four branches, three tiers each:
• Hull — more damage absorbed before you go down
• Propulsion — bigger fuel reserve and stronger thrusters
• Shields — softens hits from pirates, asteroids, atmospheres
• Weapons — auto-turret range, fire rate, plasma damage
LIVE GRAVITY PHYSICS
Real n-body gravity from stars, planets, moons, and black holes. Every flyby bends you. Plan the path you can't directly fly. Slingshots earn bonus credits the tighter your scan angle.
LOST IN SPACE
Out of fuel and drifting? You'll get a four-second warning before the run ends — enough time to decide whether to push the brake button or let the cosmos claim another pilot.
SYNTHWAVE EVERYTHING
All visuals drawn at runtime in vector code. All sound — every ping, every chord, every drone — synthesized live. No bitmaps, no recordings.
Pure offline arcade. Save persists locally. Pause anytime. Restart any system from the pause menu.
Navigate gravity. Survive space.
