If you’ve got a keyboard, you’re ready. A.K.O. — Arrow Keys Only — is a one-handed vertical roguelike. Move, dodge, and switch elements while your weapon fires automatically. It’s all about positioning, timing, and choosing the right element at the right moment. Four elements, four playstyles: Neutral — precise, tracking shots Fire — fast, aggressive spray Ice — heavy control and knockback Poison — area denial and sustain Swap instantly. Time slows for a split second — make it count. Build your run with upgrades and relics that stack into wild synergies. Freeze enemies and shatter them. Leave fire trails behind your dash. Turn poison into healing. Every run plays different. Five characters, five ways to move: Arrow — build your own kit Herald — slow, steady, hard to kill Dako — high risk, high damage Kozo — fast flight, hardest to control Mark — vertical power, strong and flexible Push deeper, take on bosses, and stack challenge modifiers like no healing, crumbling floors, or half health. Go as far as you can. Everything is procedural — visuals, music, and sound are generated in real time. No assets. Just code. The entire game is under 600KB. 4 Arrow Keys. That’s it.
