Gameplay
Actual gameplay: the title screen — “8-bit pixel princess’s dragon-slaying (or peace-making) journey”. Press Start and Princess Aila slips out of the palace at midnight with a rusted sword.
Gameplay
Actual gameplay: the opening scene — “Late at night in Brick Kingdom palace, everyone is asleep. Aila slips into the armory with her cloak…” The sword spirit is about to get a rude awakening.
Gameplay
Actual gameplay: the first choice — bicker with the sword spirit, inspect the armory, or put the sword back. Every choice builds Aila’s Sword or Heart reputation.
Princess vs Dragon (公主斗恶龙) is a playable 8-bit pixel-art adventure game generated from the 第九位元 (Ninth Bit) world in Neta Studio. Princess Aila of Brick Kingdom is tired of the “wait to be rescued” script — all 107 heroes ran away, so she decides to go herself. At midnight she draws a rusted sword from the armory, leaves her father a note — “I’ll be the hero. I’m off to slay the dragon. Mind the harvest.” — and heads north: a money-gouging goblin toll booth, a hiding knight captain, a broken bridge, and a dragon that doesn’t follow the script at all. Every choice builds her Sword or Heart reputation — and at the dragon’s lair, you decide whether she draws steel or speaks first.
Pick from the on-screen choices or type any action in your own words: bicker with the sword spirit, climb the city wall, haggle with the goblin, wake the knight. Three endings — Blood & Wheat, Dragon’s Ally, Hero Unemployed — are unlocked by the journey you choose.

Game Features
- Live LLM Narrative — Turn on AI writing and type anything for Aila — an observation, a question, a wild idea — and the LLM director answers in the moment, in each character’s own voice, from the sword spirit’s grumbling to the goblin’s toll-booth logic (deepseek-v4-flash real-time narrative).
- Sword & Heart Reputation — Every scene choice and every typed action accumulates two hidden reputations — Sword (winning by force) and Heart (winning by connection). The balance you strike decides what Aila becomes by the time she reaches the lair.
- Three Endings, One Journey — Blood & Wheat (she slays the dragon and the kingdom is safe — at a price), Dragon’s Ally (she listens first and uncovers the truth), and Hero Unemployed (she conquers the lair… and opens the hottest inn in the pixel continent).
- Free-Form Text Input — Not just buttons: type your own next move in the input bar. The game reads intent — question, banter, bluff, kindness — and each scene reacts to what you actually say.
- Authentic 8-Bit Pixel AVG — NES-era chunky pixels, a limited retro palette, black outlines, pixel dialogue boxes and square buttons with a chiptune feel — a love letter to 1980s cartridge games.
- Browser Playable, No Download — Runs instantly in your browser on neta.art, no install, no setup. Original chiptune-style BGM and a save system keep your journey safe between sessions.

Production Process Breakdown
Stage 1: World Buildingclaude-opus-5
AI receives a one-line seed prompt — “create an 8-bit style world, everything in this style, generate all the atoms directly” — and generates the 第九位元 (Ninth Bit) world: a cartridge continent running on an aging master cartridge, with six characters, six locations, four events, four factions and five world rules. Princess vs Dragon was built from that world with a single premise: a princess who refuses to wait to be rescued.

Stage 2: Game Design & Artgpt-image-2
AI designs the game from that premise: ten scenes from the midnight armory to the dragon’s lair, Sword/Heart meter progression, three endings — plus the 16:9 key art of the princess facing the red dragon over Fire Dragon Mountain, and six full-body character sprites cut out to transparent PNG via BiRefNet.

One full-body character standing centered in the frame, occupying the vertical center: a young princess in a dented iron circlet and a travel-worn indigo cloak over a short plate cuirass, holding a rust-edged shortsword low in one hand and a small burning lantern in the other, determined tight-lipped expression, pixel-art sprite proportions but full-body and detailed. A full-bleed scene background behind her: the inside of a vast dragon's forge-cavern, black basalt walls, a huge dying ember-orange firepit throwing warm rim-light, the silhouette of an enormous coiled sleeping dragon in the darkness behind, cold blue shadows against orange firelight. Near the bottom: three rounded choice buttons stacked with short action labels, and below them a wide rounded dialogue box showing a speaker name, a small progress marker, and one line of narration text, with a text-input hint row at the very bottom. Dialogue box and buttons styled as pixel-art UI panels with 1px bright borders and dark translucent fills.
