Blocktown

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 browser-based 3D third-person collection sandbox called “Blocktown Playground.” Use a bright, colorful low-poly/toy-like visual style with a sky-blue background and soft fog. The player is a stylized humanoid avatar placed on a large square green grassy island, viewed by a trailing third-person camera at an elevated angle. The camera should follow the avatar and support drag-to-look; movement should be responsive and allow jumping with gravity. Support WASD or arrow keys to move, Space to jump, and dragging the mouse/finger to look around.

Build the world as a 42-by-42 square green platform with a small raised central north-south path and crossing east-west path, both pale yellow. Add six colorful rectangular block structures around the island: red at the southwest, purple/blue at the southeast, teal at the northwest, yellow at the northeast, green near the west side of center, and pink near the east side of center. Add a line of seven blue parkour steps along the eastern side, each a square platform with progressively varying elevation, forming a simple jumping route. Place eight stylized trees around the outer edges: brown tapered trunks with simple green conical foliage. Use directional sunlight, ambient hemisphere lighting, shadows, and soft atmospheric fog.

Place exactly eight collectible glowing cyan/turquoise faceted gems, represented by octahedrons, at these world locations: roughly (-8,-8), (8,-8), (-8,8), (8,8), (-14,0), (14,0), (0,-14), and (0,0). They should float around y=1.3, gently bob up and down and rotate continuously. When the player comes within about 1.7 world units, remove the gem and increment the collection count. The goal is to collect all eight gems; there are no enemies, combat, timer, lives, or other objectives.

Use a fixed HTML overlay HUD. In the upper-left, show a dark translucent rounded panel with the bold title “BLOCKTOWN PLAYGROUND,” the subtitle “An original social sandbox slice,” and a yellow counter reading “Gems: 0 / 8” that updates as gems are collected. Before gameplay begins, show a centered coral-red rounded button labeled “PLAY BLOCKTOWN”; clicking it hides the button, starts/enables play, and focuses the game canvas. At the bottom center show a dark pill-shaped instruction label: “WASD / arrows to move · Space to jump · drag to look.” Make the layout responsive for smaller screens. Use the same clean, friendly UI typography and polished shadows as the reference, with the game filling the viewport and no scrolling.
