Mia's Adventure

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 simple third-person 3D collectible exploration game titled “Mia’s Adventure.” Use Three.js-style rendering with a perspective camera following the player from behind at roughly 6 units away and 1.5 units above the target, with the camera initially positioned behind and above the character looking toward them. The play area is a flat square green grass-like plane about 40 by 40 units, with movement constrained to approximately x/z = -18 to 18. Use a black background beyond the ground/horizon, ambient lighting plus a bright directional light from above/right, and enable soft shadows.

The player is Mia, represented by the supplied humanoid GLB model “assets/Rig_model_mia.glb,” scaled to approximately 1.8 units tall and placed on the ground. The visible character has a stylized toy/cartoon appearance: a red-and-white cap, red shirt, blue overalls, gloves, and brown shoes. Load the model asynchronously; if it is not yet available, begin with a simple blue capsule placeholder and replace it when the model loads. The supplied model has no baked animations, so keep Mia in a static pose rather than inventing a walk cycle.

Populate the field with four simple low-poly trees used as scenery: brown cylindrical trunks and rounded green spherical foliage, placed around the edges/various locations. Add four brown wooden-looking cube obstacles, each about 1.5 by 2 by 1.5 units, at scattered positions. The obstacles cast and receive shadows and are dangerous: if Mia gets within about 1.8 units of an obstacle, immediately show a centered “Game Over” overlay and stop gameplay. Also end the game if she falls below y=-2, although ordinary movement should keep her on the ground.

Place eight small golden spherical collectibles at random positions across roughly a 30 by 30 area, each hovering around y=1.5. They should have a bright gold material with a subtle emissive glow. When Mia comes within 1.2 units of one, remove it, add 10 points, update the score, and immediately spawn a replacement collectible at another random position, so the field continues to contain collectibles. The winning goal is a score of 100; at 100 or more, stop the game and show a centered “You Win!” overlay.

Implement movement through a third-person control system: WASD and arrow keys move Mia, Space makes her jump with jump speed around 9 and gravity around -22, and movement speed is around 6. Clicking the canvas locks the mouse/pointer for camera look. On touch/mobile presentation, provide the circular translucent virtual joystick/control visible at the lower-right as in the reference. Keep the player within the square boundary and prevent her from sinking below the ground during normal play.

HUD/UI should be minimal and match the reference: in the upper-left, show white text “Score: 0” initially, using a clean sans-serif font with a slight dark text shadow. Along the bottom center, show a small semi-transparent black rounded rectangle containing white instructions: “WASD / Arrows: Move   Space: Jump   Click to lock mouse.” When the game ends, display a large centered white “Game Over” or “You Win!” message over a dark translucent rounded panel with a “Play Again” button beneath it. Clicking Play Again reloads/restarts the game. The scene should feel like a basic low-poly cartoon 3D playground: green ground, black surrounding background, simple geometric trees and wooden blocks, strong directional shadows, and the colorful static Mia character as the visual focus.
