MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Reversi / Othello". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Create a sleek, realistic table-top aesthetic. The environment should feel like a premium game room with a focus on the board. * **The Board**: A slightly reflective black base with an 8x8 grid of vibrant green squares (use a felt-like texture or a matte green material for contrast against the shiny pieces). The board edges should look like polished plastic or dark wood. * **Game Pieces (Discs)**: Create cylindrical discs that are white on one side and black on the other. Use a slightly glossy material (like polished stone or plastic) that catches the light. * **Animations**: Crucial for game feel. When a piece is captured and flips color, implement a smooth 180-degree flip animation (rotate along the X or Z axis) that shows the two-sided nature of the disc. Do not just swap the color instantly. * **Environment**: Place the board on a warm, dark wooden table surface. Add a soft spotlight focused on the center of the board to create dramatic shadows and highlights, fading into darkness at the screen edges to save rendering resources on mobile. * **Optimization**: Use low-poly cylinders (e.g., 16-24 segments) for the discs to maintain high frame rates on mobile devices. ### 2. Audio Requirements * **BGM**: A calm, jazzy, or ambient lounge track that promotes thinking and relaxation. It should be subtle and loop seamlessly. * **Sound Effects**: * *Placement*: A satisfying "clack" sound of a hard plastic piece hitting a board. * *Flipping*: A quick, soft "whoosh" or a cascading clicking sound when multiple pieces flip in a row. * *Invalid Move*: A low-pitch, subtle thud or buzz indicating a move is not allowed. * *Game Over*: A short, triumphant jingle for the winner and a neutral or slightly melancholic tone for the loser. ### 3. Gameplay Loop * **Core Logic**: Implement the standard 8x8 Othello/Reversi rules. The game starts with two black and two white discs in the center in a diagonal pattern. * **Turn System**: Players take turns placing a disc of their color on the board. A valid move must "sandwich" one or more opponent's discs between the new disc and an existing disc of the player's color. * **Flipping Mechanism**: Upon a valid move, all sandwiched opponent discs are flipped to the current player's color. This must update visually via the animation described above. * **AI Opponent**: Include a simple Minimax algorithm or a greedy AI for single-player mode that prioritizes corners and edges. * **Win Condition**: The game ends when the board is full or neither player can make a valid move. The player with the most discs of their color on the board wins. * **Valid Move Indicator**: To assist players, subtly highlight valid grid squares (e.g., with a small translucent dot or a glow effect) when it is their turn. ### 4. Mobile Controls & Interaction * **Orientation**: Portrait mode is preferred for one-handed play, but the camera should be positioned at a comfortable angle (approx 60 degrees) to see the board depth while maximizing screen usage. * **Input**: Tap-to-place. The grid cells should have generous hitboxes. When a player taps a valid square, the piece is placed immediately. * **Camera Controls**: Disable free camera rotation to prevent the user from getting lost. Allow slight pan/tilt based on device gyroscope (if available) for a parallax 3D effect, or a very limited touch-drag to inspect the board. * **UI Layout**: * Top of screen: Scoreboard showing current disc counts (Black vs. White) with large, readable numbers. * Bottom of screen: A "Restart" button and a "Pass" button (only active if no moves are available). * Buttons should be at least 44x44px for touch accessibility. * **Haptic Feedback**: Trigger a light vibration (using the Vibration API) when a piece is placed and a heavier vibration when the game ends. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
