About

Substrate Entity

Features
Read full description

You are a charge running an etched plate. The trace splits under you, and some of the branches it offers are already finished. Nothing marks them. You read ahead, you pick a side, you keep moving. Press the left or the right of the glass. That is the whole game. SEVEN STRATA Each one runs faster and darker than the one above it. When the colour turns, the tempo turns with it. CHARGE Every row costs you. The bright pads pay it back and stack your multiplier. The branch that keeps you alive and the branch that keeps you fed are rarely the same branch. NO ADS No timers, no energy, no currency, no in-app purchases, no account. It runs entirely on your phone. Portrait, one thumb. Sound, haptics and motion each turn off. More from Dro1d Labs: Pixel Pigeon for the stubborn life of a city bird, and War Pigeon for tactical stealth after dark.

About

Rev Rush

Read full description

Twist the throttle and go. Rev Rush is a one-tap pixel runner where the speed keeps climbing, every jump counts, and a heart hidden in every world might just save your run. RIDE THROUGH 21 WORLDS From sun-baked desert into the night, through storms, snow, the open sea, and the mountains. Survive the volcano, blast through space, cut through the jungle and the neon city, storm the castle, dive underwater, cross New York, climb sky-high, escape the factory - then on through the forest, the kids’ room, the bat cave, the toxic swamp, the glacier, and the magic forest. Every world has its own obstacles, sky, and soundtrack. ONE TAP. THAT’S IT. Tap to jump. Clear the gaps, dodge the obstacles, land clean, and keep the throttle open. Instant response and jump buffering keep every crash fair - no waiting, no second button to learn. TEN WAYS TO DIE, NOT FOUR Every world owns a signature move - a needle’s eye only an early jump threads, a stalactite that drops as you approach, chandeliers swinging on a rhythm, pistons erupting out of the floor, ice that cracks under your wheels. And in every world a racer of its own storms in from behind: watch the edge at your back. A HEART IN EVERY WORLD Each of the 21 worlds hides a heart, and each one moves its own way - it parachutes down, swings on a vine, rides a bubble, or slides out of a glacier crack. Catch it for an extra life, up to three. A heart even catapults you back out of a hole. Fill your heart album with all 21 and every run starts with an extra revive - for good. BUILD YOUR COMBO Chain coins for a multiplier up to x5. Shields bounce down the road and shooting stars dive from the sky - time your jump to grab them. A shield takes a hit for you; a star gives 2.5 seconds of TURBO that smashes obstacles and pulls in coins like a magnet. Every 7th heart or star in a run earns a revive. SPEND WHAT YOU EARN Coins are your in-game currency. Buy bike skins, themed trails that throw each world’s own material off the rear wheel, or a shield, a life, or a revive on the start line - and switch them off for a clean, unassisted score. CLIMB THE GLOBAL PODIUM The top three stand full-size on the podium, wheels still spinning, in the exact colors they rode. The rest of the top 100 fill the column beside them. Each vehicle has its own leaderboard, and every run can be shared as a poster. LATER LAPS ARE A REMIX Ride all 21 worlds and everything flips: you race right to left, obstacles turn cold blue and start to bob, and the timing tightens all over again. BUILT FOR IPHONE DUO AND IPAD Closed, iPhone Duo plays like any iPhone; open it and the ride fills the big inner display. Fold or unfold mid-ride and the run waits for you. Half-open like a book or a laptop, every button stays off the fold. iPad and iPhone Duo also play in portrait. FEATURES • One-tap controls tuned for a perfect “one more run” feel • 21 hand-crafted pixel worlds on an endless loop, each with its own music • A full “How to play” guide, fully localized in 20 languages • Play offline anywhere — zero ads, zero interruptions PREMIUM - ONE OPTIONAL UNLOCK It unlocks the Hover, which adds a second tap: one to leave the ground, one more in mid-air to push higher. Same speed, same worlds, its own leaderboard. And Haptic terrain: feel the road in your hands. Every world rumbles its own way - sand hums, gravel shakes, ice cracks, the factory pounds - and it goes quiet the moment your wheels leave the ground. On iPhone. Plus Teleport (start in any world you’ve reached), the garage’s 51-color paint shop, access to the direction change (ride right to left), every coin-store skin and trail, a shield, a life, and a revive from your first run, a rainbow trail, a star glow, and a gold crown beside your name. Premium hands you those items sooner, never an unfair advantage: the same shield, life, and revive limits apply to everyone, so the leaderboard stays about skill, not receipts. Helmet on. Throttle open. How far can you ride?
