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 playable 3D third-person endless platforming game titled “Blockbound Endless.” Use a full-screen WebGL-style scene with a bright sky-blue background and matching distance fog, soft shadows, and simple clean low-poly/blocky visuals. The camera should be a perspective camera following closely behind and above the player, looking along the forward course; nearby floating blocks appear larger than distant ones.

The player is a compact Roblox-like block character made from simple primitive meshes: a square head with a hair cap and two tiny front-facing eyes, a blocky torso, two arms with round hands, and two separate legs with feet. Keep the character’s collision/movement body the same while allowing three visual avatar choices from the HUD: yellow avatar (yellow shirt, blue pants, peach skin, brown hair, dark eyes), red robot (red shirt, gray pants, pale metallic skin/hair, cyan eyes), and blue ninja (blue shirt, very dark pants/hair, orange skin, white eyes). Clicking an avatar button immediately swaps only the visible character and marks the selected button with a white outline.

The core goal is to run and jump forward across an endlessly generated chain of floating rectangular platforms without falling into the void. Begin the player on a large green starting platform at the origin. The course extends forward on the positive Z axis. Generate additional platforms procedurally as the player advances, keeping a playable gap between each block: platforms should be randomly offset left/right within a bounded corridor, vary modestly in height, and use varied rectangular widths/depths. Use colorful platform materials such as red, orange, purple, cyan, and pink, with the start platform green. Keep generation ahead of the player and remove distant platforms behind the player so the course remains endless without accumulating objects.

Movement should support WASD and arrow keys for movement, with Space for jumping. Use responsive third-person character physics: approximately 7.2 movement speed, 10.5 jump speed, downward gravity around -25, and collision/landing on the floating blocks. The player can move laterally to line up landings and jump across gaps. If the player falls below the world, reset them onto the nearest safe platform that is horizontally reachable and behind or beneath their current position, and display a status message explaining that they fell and were reset. Do not end the game; the run continues.

Build the HUD as a translucent dark navy rounded panel in the upper-left corner with a thin semi-transparent light border, subtle shadow, and readable white text. Show the title “Blockbound Endless,” the instruction “Jump across the floating blocks forever.”, the yellow-highlighted control hint “WASD / Arrow keys: move · Space: jump,” and a bold distance counter starting at “Distance: 0 m.” Include an “Avatar:” row with three small square buttons for Yellow block, Red robot, and Blue ninja, with the yellow option initially active. Include a green status line that initially says “Start running forward to generate the course.”, changes to indicate the selected avatar, reports that new platforms are appearing while moving, and reports the nearest-platform reset after a fall. The distance score should track the maximum forward Z distance reached from the start, in whole meters, so it does not decrease when the player moves backward or falls. The game should feel like an infinite colorful floating-block obstacle course, with no weapons, enemies, collectibles, timer, or other mechanics beyond movement, jumping, landing, procedural platforms, avatar selection, distance, and fall recovery.
