Anima Dating Sim

Cinevva's analyzer read this game's design doc and its source, then wrote the brief below. "Make your own" hands it to the game creator as your opening message, so you start from a real spec rather than a one-line idea.

Create a mobile-first browser visual novel/dating sim titled “Anima Dating Sim.” The game is a short, choice-driven romance game with two selectable-through-replay routes: Aiko and Reina. A playthrough has 5 sequential days/scenes, one choice per day, then a stat-based ending. The player taps/clicks one of three choice buttons, or presses keyboard 1, 2, or 3. On the ending screen, a full-screen “Play again” button starts a fresh run on the other route; keyboard R does the same route switch. Do not add a title screen or route-picker: the initial run begins directly on Aiko Day 1, and replay switches Aiko to Reina or Reina to Aiko.

Presentation: render a dreamy nighttime school courtyard in Three.js behind the interface. Use a dark purple-to-black atmospheric sky with fog, a pale moon high on the left, a dim circular ground plane, and stylized pink cherry blossom trees/canopies framing the scene on both sides. Animate around 90 small pink petals drifting downward with sideways movement and rotation, plus about a dozen faint translucent floating heart sprites. Give the camera a subtle slow sway and the blossom arch a slight rotation. Aiko’s route should use warmer violet/pink sky colors, a warm pale moon, and blue fill light; Reina’s route should shift the sky toward deep blue and the moon toward cool white. Let affection, confidence, and charm subtly increase heart visibility/environment brightness, but keep the dialogue UI readable above the scene.

Overlay a glassmorphism HUD over the full viewport, using rounded translucent dark-purple panels, white text, pink/blue/purple gradients, soft shadows, and responsive mobile layout. At the top show chips for “Route Aiko/Reina” and “Day 1/5” through “Day 5/5”; show three stat chips labeled “Affection,” “Confidence,” and “Charm,” all starting at 0. In the central/right area show a route-colored stylized character portrait made from simple graphic shapes/gradients rather than requiring external character art: a rounded rectangular pink-to-purple card, pale face/body, dark hair cap, simple eyes and mouth, and a glowing circular highlight. Under/near it show a rounded mood pill. On desktop the portrait is at the right above the dialogue; on narrow mobile screens it is centered and the choices stack vertically. The bottom dialogue panel is a large rounded translucent dark card. It contains a gradient nameplate in uppercase (“AIKO” or “REINA”), a large serif-like narrative line, a smaller muted subline, three large choice buttons, and helper text “Tap a choice — or press 1, 2, 3.” Buttons have distinct gradients: choice 1 pink/purple, choice 2 blue/indigo, choice 3 orange/pink. Each button shows numbered choice text and a smaller effect hint.

Game state: routeKey is aiko or reina; dayIndex 0–4; affection, confidence, charm numeric stats; lastResponse; gameOver; and ending. Each choice immediately adds its effects and shows its response as the next displayed dialogue while advancing to the next day. On the fifth choice, stop advancing, calculate the ending from the accumulated stats, hide choices, and show a centered modal over a blurred dark overlay. The ending modal has a title, descriptive text, and “Play again.”
