TUNL

Eternal Labyrinth

A hold-to-thrust cave flyer. Hold to climb, release to fall, and see how far you can push into the dark before the tunnel closes in.

New in 3.2: rare wall-mounted cannons join the hazards, plus two new coins - a toxic green one that costs you shards if you grab it, and a purple one that detonates a small blast to clear the danger around your ship.

Hold. Release. Survive.

Features

🌀

A tunnel that never repeats

Procedurally generated corridors get tighter and faster the deeper you go, so no two runs feel the same.

đŸĒ™

Six power-up coins

Gold widens the corridor, blue slows time, red shields a hit, orange loads ammo, green pulls coins toward you, and purple detonates a blast that clears nearby danger.

âš ī¸

Stalactites, mines, and cannons

Sharp obstacles, paired chicanes, and rare wall-mounted cannons that fire warning shots force split-second calls as the run speeds up. Watch out for the toxic green coin too - it looks like a pickup, but it costs you shards.

🏆

Milestones and combos

Chain coins for score multipliers, thread close calls for bonus points, and celebrate every milestone in style.

💎

Shard economy

Coins you collect bank into shards, a persistent currency shown right on the home screen. Daily earning is capped, so unlocking the full roster takes steady daily play, not one grind session.

đŸ›Šī¸

Every ship, a real build choice

7 ships, each pairing a buff with a drawback, from the free PEARL starter up through AMBER, CRIMSON, ELECTRIC, TOXIC, VOID, and NOVA. Fly one enough and it gains mastery, easing its drawback and growing its buff.

📋

Daily missions

3 fresh challenges every day, the same for every player, each one worth a shard bonus on top of your daily cap.

đŸ—“ī¸

A new level every day

The title screen names every calendar day its own level, like "LEVEL 231: RUSTED CAVERN," with a slightly different corridor shape each time.

📈

Chase your best

Every run compares against your last and your personal best, with daily streaks, a Game Center leaderboard, and iOS Challenges to keep you coming back.
