Final Product: Hogwarts: Pixel Spell Brawl (霍格沃茨：像素魔咒乱斗)
Cover
Key art for the game, generated in 16:9: the Great Hall under a starry enchanted ceiling, floating candles, house banners, and two young duelists with raised wands — the whole match in one frame.
Gameplay
Real gameplay, title screen: "HOGWARTS — PIXEL SPELL BRAWL", "Hogwarts Duelling Club", the tagline "Six wizards. One Great Hall. Best of three." and the ENTER DUELLING CLUB button over a painted pixel Great Hall.
Gameplay
Real gameplay, roster: "CHOOSE YOUR WIZARD" — six pixel duelists in a row (Harry, Hermione, Ron, Draco, Snape, McGonagall), each card showing house and role, with Harry's tag #MAIN CHARACTER ENERGY and his signature spell Patronus Rush below.
Gameplay
Real gameplay, mid-duel: Harry vs Ron in the Great Hall with HP and mana bars, the 57-second round clock, round pips and an explosive Bombarda lighting up the duelling floor.
Hogwarts: Pixel Spell Brawl (霍格沃茨：像素魔咒乱斗) is a playable 16-bit pixel-art duelling game set in the Harry Potter wizarding world. Six familiar fighters step onto the Great Hall floor for a best-of-three: Harry Potter, Hermione Granger, Ron Weasley, Draco Malfoy, Severus Snape and Minerva McGonagall.
Pick a wizard and the game pairs you with a random AI rival. Each round lasts sixty seconds: drain your opponent's HP, or lead on health when the clock runs out, and take two rounds to win the match. Attack with three spells — Stupefy (a fast bolt), Expelliarmus (a heavy close-range beam) and each fighter's signature spell, which costs 50 magic but can flip a round: a Patronus charge, a Glacius freeze, a chaotic Bombarda, a venomous Serpensortia, a Sectumsempra slash, or McGonagall's animated desks and chairs.
Magic regenerates slowly and holding away from your opponent softens incoming hits, so every round is a small duel of spacing, timing and nerve. The whole thing plays with the keyboard (A/D move, W jump, J/K/L cast, P pause), on-screen touch controls on a phone, and ships with an English/中文 toggle. Every tagline, quote and meme line — "The prophecy has entered the chat.", "Minus ten points." — is written in both languages.

Game Features
- Live LLM Narrative — Every fighter's tagline, victory quote and meme line, plus the round and match callouts, was written and tuned with the deepseek-v4-pro language model in both English and Chinese, so the Great Hall keeps talking from the first "ROUND 1" to the final "DUEL WON".
- Six Wizards, Six Fighting Styles — Harry (Gryffindor · Balanced · 110 HP), Hermione (Gryffindor · Control · 100 HP), Ron (Gryffindor · Burst · 116 HP), Draco (Slytherin · Speed · 96 HP), Snape (Slytherin · Pressure · 108 HP) and McGonagall (Gryffindor · Defense · 122 HP), each with their own speed, health and personality.
- Best-of-Three Duelling Loop — Sixty-second rounds on a clean arena floor. Drain your rival's HP or lead on health at the buzzer to take the round; take two rounds to win the match, then REMATCH or CHOOSE AGAIN from the result screen.
- Three Spells & a Magic Meter — Cast <strong>Stupefy</strong> (fast light bolt), <strong>Expelliarmus</strong> (heavy close beam) and your <strong>signature spell</strong> for 50 magic. Mana refills slowly, hitstun and knockback matter, and holding away from your opponent cuts incoming damage — a guard, not just a brawl.
- Six Signature Spells — Patronus Rush (a rushing spirit hit), Glacius (freeze and slow), Bombarda (an oversized chaotic blast), Serpensortia (a venomous serpent that poisons), Sectumsempra (a sweeping red slash) and Piertotum Locomotor (animated furniture plus a self-heal shield).
- Bilingual Pixel UI, Great Hall Arena & Touch Controls — A one-tap English/中文 toggle, a chunky pixel HUD with HP, mana, timer and round pips, a 2048×1152 hand-pixeled Great Hall stage, and on-screen touch controls so the duel plays the same on a phone as on a desktop keyboard.

Production Process Breakdown
Stage 1: World Buildingclaude-opus-5
From the one-line seed 哈利波特, the world compiled 136 atom cards — 49 characters (Harry, Hermione, Ron, Dumbledore, Snape, Voldemort, McGonagall, Hagrid and more), 45 locations (the Great Hall, Diagon Alley, the Black Lake, the Forbidden Forest, Gringotts, the Burrow), 22 lore rules (Horcruxes, the Deathly Hallows, the four houses, the Order of the Phoenix), 14 events, 3 secrets and 3 perspectives — all pinned to canonical Harry Potter lore.

Stage 2: Game Design & Writingdeepseek-v4-pro
The seed became a best-of-three duelling loop: six fighters with distinct houses, roles, health, speed and signature spells; a three-spell combat kit with a slow-refilling magic meter, hitstun, knockback and directional guarding; a sixty-second round timer; and a bilingual English/中文 voice layer of taglines, quotes, meme lines and round/result callouts.

Stage 3: Pixel-Art Asset Productiongpt-image-2birefnet-general
Six full-body 16-bit duelist sprites were generated with GPT Image 2 on a solid magenta chroma key, then six signature-cast action poses (Harry's forward Patronus cast, Hermione's rulebook-and-ice glyph, Ron's oversized Bombarda, Draco's emerald serpent, Snape's red slash, McGonagall's animated furniture). A 2048×1152 Great Hall arena was painted for the runtime, and every figure was cut to a clean transparent PNG with BiRefNet.

Stage 4: Browser Packaging & Publishgpt-image-2neta-studio
The sprites, arena, three-spell combat, AI opponent, bilingual UI and touch controls were packaged into a single static browser game rendered on a 960×540 pixel canvas, then published with one click as a shareable link. The 16:9 key art on this page was generated for the release.

Scene Backgrounds
BG
The game's real arena: a 2048×1152 side-view pixel Great Hall — long stone chamber, floating candles, four banquet tables pushed to the sides, tall gothic windows open to the night sky and an enchanted star ceiling, with the central duelling floor kept clear.
BG
The world's canonical Great Hall art — the reference scene the pixel arena was built from, with the starry ceiling, banners and long house tables that the game re-pixelled.
BG
Canonical world scene: the castle above the Black Lake at moonrise — one of the wizarding-world locations the duelling club is set inside.
BG
Canonical world scene: the Grand Staircase with its portrait-lined walls — the castle's other great interior, kept as scene reference alongside the Great Hall arena.

World Visual Target · neta-studioneta-studio
World art direction (from the world manifest): vintage storybook fantasy oil painting — visible painterly brushwork with strong chiaroscuro, one dramatic light source carving deep shadows and luminous highlights; a cool emerald-and-silver moonlit palette for night scenes with rich silver moonlight and deep blue-black shadow; mystical, ancient storybook atmosphere; textured painterly surfaces and a refined illustrated-book finish. For this game the world style was re-pixelled into an authentic 16-bit retro RPG look with chunky readable pixels, crisp dark outlines, a limited palette and a consistent scale across every fighter. World seed: 哈利波特 (Harry Potter).
