Read full descriptionHide full description
Pilot through ten star systems on a single trajectory. Aim, launch, slingshot โ 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 โ 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 โข Tap and drag from the ship to aim and set power โข A live trajectory preview shows the gravity-bent path before you commit โข Mid-flight: tap anywhere to fire navigation thrusters perpendicular to your heading โข 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 โ 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: โข Hull โ more damage absorbed before you go down โข Propulsion โ bigger fuel reserve and stronger thrusters โข Shields โ softens hits from pirates, asteroids, atmospheres โข Weapons โ 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 โ 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 โ every ping, every chord, every drone โ 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.

Verdict
The clearest difference is in-app purchases: Delta at none against Kolf's 1. Delta also leads on ads (none vs shown). Kolf's advantage is iOS requirement (12.0 vs 14.0). On price and device support there is nothing between them.
