Birthday Flower Hunt is a playable 30-second birthday mini-game generated from a one-line seed prompt in Neta Studio: a cheerful chibi anime girl runs free across a small cel-shaded garden and picks every flower, heart, balloon and chocolate she can reach before the timer hits zero. 30 seconds. One tiny garden. As many flowers as you can grab.
Walk into a pickup to collect it — or tap one and she runs to grab it herself. Pink, yellow and red smiling flowers are worth 10 points, glossy hearts 15, floating balloons 20 and wrapped chocolates 25. Cross 600 points and she powers up for the rest of the round — 1.5× speed, a glowing golden aura, a crown glint and a confetti burst — while the 400 and 800 marks roll a soft mist over the garden to hide the field for a while. Every milestone fires a cheer, the round ends with a one-to-three-star rating, and your best score is saved to chase next time.

Game Features
- Live LLM Narrative — the world and the arcade loop were designed live by an LLM from a single sentence, then assembled on Neta Studio's real-time AI pipeline (deepseek-v4-flash real-time build). From the seed line to a finished, playable game.
- 30-Second Flower Rush — Race the clock across one small garden: flowers, hearts, balloons and chocolates spawn across the lawn and disappear again after a few seconds, so a whole round is a cheerful sprint. When the timer reaches zero the final score is shown.
- Cute Point Pickups — Pink, yellow and red smiling flowers are worth 10 points, glossy hearts 15, floating balloons 20 and wrapped chocolates 25 — the rarer the pickup, the faster you have to be.
- POWER UP at 600 — Cross 600 points and the heroine powers up permanently for the round: 1.5× movement speed, a glowing golden aura, a crown glint and a confetti burst. Hit 400 and 800 and a soft mist rolls in to hide the garden for a while.
- Cheers, Stars & Best Score — Every milestone fires a cheer — 100, 200, 300 ... 1000 — and the round ends with a one-to-three-star rating and your saved best, so there is always a score to beat.
- Browser Playable, One Tap — Runs straight in the browser with no download. Move with WASD or the arrow keys on desktop, or tap and drag on the lawn — tap any pickup and she runs over to collect it herself.

Stage 2: Game Design & Artgpt-image-2
AI designs the arcade loop — 30 seconds on the clock, random spawns, 10/15/20/25-point pickups, milestone cheers, the 600-point power-up and the mist windows at 400 and 800 — and draws all 14 art assets on plain white backgrounds with GPT Image 2: the heroine, her powered form, three smiling flowers, a heart, a balloon, a chocolate, a cake, bunting, the garden lawn and two mist textures.

Stage 3: Sprite Cutoutsbirefnet-general
Every character, pickup and decoration is cut from its white studio background to a clean transparent PNG with BiRefNet, so the sprites drop onto the garden lawn with no matte edges or haloes.
