Are you ready for a unique adventure like no other? Oxytone invites you to explore the depths of your mind while offering a tranquil escape from the hustle and bustle of everyday life for those seeking relaxation. For more determined players, there are 99 challenges, colorful themes to unlock, and 12 meticulously designed maps. Oxytone is the ultimate puzzle game, equally easy to learn and challenging to master. Strive for the highest scores by creating the longest paths and achieving impressive combinations. Every move matters, and success depends on strategy and planning. You can discard tiles that don't fit your plan, but this reduces your pool of available tiles. To refresh it, you must fill tiles by guiding paths through them six times, deepening the mechanics further. Sound is an integral part of Oxytone, so I recommend playing with headphones. This will immerse you even deeper into the game. The sound design has been crafted with great care to create a unique and relaxing atmosphere, yet it can also deliver powerful moments when needed.

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.

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