A.K.O

Arrow Keys Only

Out now on Steam. A one-handed vertical roguelike shooter where your weapon fires itself; you move, dodge, and swap elements to survive the climb.

One hand. Five pilots. Seventy-five skins.
Everything generated from code at runtime.

A.K.O key art showing a neon vertical climb, arrow controls, platforms, and elemental hazards

The climb is open. Your arrow keys are enough.

Auto-fire keeps the screen honest. Movement, timing, route choice, relic synergy, and elemental reads do the rest.

  • Out now on Steam with a 20% launch discount.
  • Launch sale: $3.99, normally $4.99.
  • Free demo available if you want to try the controls first.
  • Windows and macOS builds, controller friendly.

Read the Room Before It Reads You

Each procedural climb shifts its platforms, enemies, atmosphere, hazards, and relic bias so the route has a real identity.

Start
SIGNAL SPIRE
Neutral · Learn the climb

Clean lines, signal ghosts, and enough room to understand the rules before the dungeon starts squeezing.

Ice
FROZEN CRAG
Rival · Ward

Aurora curtains, drifting ice peaks, icicles on every wall. Slow. Heavy. Every shot lands like a brick.

Fire
BURNING HEART
Rival · Kite

Factory skyline, sparks, and heat pressure. Fast lanes, burning crumbleways, and very little time to admire them.

Poison
JUNGLE TOXICA
Rival · Mark

Mushroom forest, hanging vines, bioluminescent bloom. Overgrown platforms that cling back at your boots.

Void
DIGITAL URN
Rival · Gaze

Nebula clouds, circuit grid, holographic cubes drifting through the dark. Fast vectors. Tighter lines. No safety net.

Read the Enemy. Match the Element.

Weak-matched hits deal 1.75×. Resisted hits deal 0.45×. Every enemy has its own weak and resist — switching correctly is the game.

Neutral
Paint / Setup

Low damage by itself. Paints the target for +25% amp — swap to fire / ice / poison and every follow-up hits like a boulder.

Fire
Burst / DoT

Highest sustained DPS. Burn ticks after the hit. Short spread, fast cadence.

Ice
Control

Heaviest per-shot. 55% slow + real knockback. Brittle combo for crushing burst.

Poison
Area Denial

Lingering DoT + impact clouds. Spread via Contagion, linger via Miasma.

Unlock. Dress up. Switch.

Each pilot starts with a signature move. Every run chips toward new skins — road signs, hand-drawn kid crayons, solar flares, censers, six-winged seraphim, marquee lights. Seventy-five drip looks across the roster.

PICK
The starter · drafts movement
WARD
Innate glide · regen while still
KITE
Innate dash · dash deals damage
GAZE
Innate jetpack · +25 speed
MARK
Innate double jump · high ceiling

Pilot Rank

PILOT RANK 8

A universal meta XP track. Every run ticks it — death or victory, first wave or final boss. 50 ranks to chase, visible everywhere, never lets a run feel wasted.

Trials & Sigils

Stack rule mods on any run. Volatile makes enemies explode. Fragile halves your HP. Reaper spawns a dark echo. Clear runs with them active to earn sigils.
