Every universe obeys different laws.

A 2D top-down survivor where mastering one world teaches you nothing about the next. Survive, adapt, claim the Keys and face a finale built from the worlds you chose.

Get it on Steam Android coming soon

You are the Engineer

A drifter between worlds. Each universe is a 15-stage journey on a stage map: survive until the timer ends, then walk into the exit portal. A mini boss waits halfway, the final boss at stage 15. Your build grows from a single weapon into a screen-filling arsenal, then resets when you cross into the next world. Three Keys open the Center.

Four worlds, four rules

Mastering one world teaches you nothing about the next. Pick a world to watch it in action and learn how its law works.

Law: Tank

Voxel

A world of stone blocks and moss where mass is armor. Grow big and the blocks stop hurting.

How it works

  • The bigger you are, the less damage you take: at 1.5× size hits deal 25% less, at 2× size they deal 50% less.
  • When the armor saves you, ARMOR −X% flashes above your head.

Waves

Enemies march in like masonry: compact squares first, then staggered brick rows, and finally a deep block wall.

Tips

  • Pick size upgrades here. In Voxel, size is armor.
  • Orbit, area and fire weapons show up more often in Voxel's level-up cards.
  • Keep moving anyway: armor softens hits, it does not stop them.

Law: Parity

Number

A world of numbered tiles and math symbols where enemies take sides. Read the color, not the number.

How it works

  • BLUE (even) enemies take full damage from everything.
  • ORANGE (odd) enemies resist direct hits: bullets deal only 35% to them, while area damage from auras, explosions and chains deals 120%.
  • Orange enemies are not immune. A pure bullet build still wins, just slower.

Waves

Formations trace math: the first act arrives as a y = x² curve, later acts ride sine waves.

Tips

  • Carry at least one area weapon (aura, explosion or chain) for the orange ones.
  • Let bullets clear the blue enemies and let area damage handle the orange.
  • Area, chain and explosion cards show up more often in Number's level-up cards.

Law: Combo

Retro

An 8-bit arcade in deep space. Kills without getting hit stack into raw power.

How it works

  • Every kill adds to your combo. Every 8 kills give +1 damage to all your weapons, up to +4 at 32 kills.
  • A hit from an enemy resets the combo, and so does standing still for about a second. Field hazards do not break it.
  • Your current combo and its damage bonus are shown on screen.

Waves

Enemies fly in like a classic arcade shooter: wide invader rows, then diving wedges, then dense zig-zag fleets.

Tips

  • Move in wide loops. Never stop to aim; your weapons fire on their own.
  • Kill fast and take no hits: +4 damage on every weapon is a huge boost early in a run.
  • Projectile, chain and explosion cards show up more often in Retro's level-up cards.

Law: Momentum

Alien

A jungle of purple mushrooms and alien crystals under heavy gravity. The swarm wants you to stop.

How it works

  • Heavy gravity: you pick up speed and change direction more slowly, so plan your path a step ahead.
  • Alien enemies are bigger and come as a swarm.

Waves

Loose at first, then crescents gathering along one edge, and finally a full hive ring that closes around you.

Tips

  • Keep a wide circle path. Stopping lets the ring close.
  • When the ring closes, break out through its thinnest part instead of waiting.
  • Homing, slow and chain cards show up more often in Alien's level-up cards.

What's inside

Three stars per stage

Clear it, clear it without dying, clear it with little damage. The final boss needs 21 stars, so replay stages to earn more.

3 lives per universe

Run out and that universe starts again from stage 1. Your stars stay.

Adaptive finale

The Center bosses mirror the Keys you collected, so every campaign ends differently.

Danger levels 0–5

Tougher enemies, richer rewards and deeper unlocks in every universe.

Synergies and evolutions

Weapon synergies, evolutions and wild cards. Build for the universe, not the meta.

English & Türkçe

Fully playable in both languages, with more languages on the way.
