A.K.O - Arrow Keys Only

If you've got a keyboard, you're ready.

A.K.O is a vertical roguelike shooter built around one rule: you only use the arrow keys.
Your weapon fires automatically. Your job is everything else: move, dodge, read the room, swap elements, pick relics, and keep climbing when the screen starts getting rude.

Four elements, four playstyles

Tap DOWN to swap elements. Time hitches for a split second so you can make the read.

Neutral paints targets for follow-up damage.

Fire burns fast and hits hard.

Ice slows, shoves, and sets up shatter damage.

Poison leaves clouds, spreads pressure, and turns space into a weapon.

Match an enemy's weakness and you hit harder. Fire into a resistance and you will feel it immediately.

Runs that actually change shape

35+ relics stack into synergies. Freeze enemies and shatter them. Leave fire trails behind your dash. Turn poison into healing. Two runs never feel the same.

Five pilots, five ways to move
Pick — build your own kit

Ward — slow, steady, hard to kill

Kite — high risk, high damage

Gaze — fast flight, hardest to control

Mark — vertical power, strong and flexible

Push deeper through five procedural dungeons and their bosses. Layer on challenge modifiers — no healing, crumbling floors, half HP — and see how far you get.

All procedural

Visuals, music, and sound are generated from code at runtime. No assets. The entire shipping build is 11 MB.
