Fence Finder

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 3D browser baseball timing game titled "Fence Finder" using a Three.js-style scene and a fixed perspective camera positioned behind home plate, looking toward center field. The setting is a stylized baseball diamond at night: use a deep navy background with atmospheric fog, a broad green grass field, a brown dirt infield, white foul lines running toward the outfield, a white home plate in the foreground, a dirt pitching mound in the distance, and a dark teal outfield fence spanning the horizon with evenly spaced posts and a dark center scoreboard panel. Light the scene with soft cool ambient light and a warm directional key light, with visible shadows.

Place a simple low-poly batter centered near home plate: a brown cylindrical lower body/leg, a blue cylindrical torso, and a skin-colored horizontal cylindrical head. Include a brown/orange bat held to the batter's right side, initially angled across the body. A white baseball with red seam arcs should pitch directly toward the camera/batter from deep center field. The ball starts around z=-10 at y=1.45 and travels toward the batter at z about -0.15 over roughly 2.35 seconds on the first pitch, becoming slightly faster on later pitches (minimum about 1.75 seconds). Add a small side-to-side sine-wave drift and slight vertical arc, plus visible ball rotation.

Show a translucent gold timing zone as a narrow horizontal strip on the ground just in front of the batter, centered around the ball's contact depth, with small gold tick marks. The core mechanic is timing the swing: the player presses Space or taps/clicks a large on-screen SWING button while the moving ball crosses this gold zone. Only allow one swing per pitch. Calculate timing based on how close the ball is to the center of the zone: excellent timing produces a random-distance HOME RUN result (roughly 365-850 feet), good timing produces a DEEP FLY (roughly 140-320 feet), and poor timing produces either SWING AND MISS or, if somewhat closer, FOUL TIP. A pitch that reaches the batter without a swing is a CALLED STRIKE. After showing the result briefly, advance to the next pitch and reset the ball; play exactly 10 pitches total. Accumulate hit distances in the score; misses and strikes add no distance. On the tenth pitch, stop play and show FINAL: [total] FT, hide the swing controls, and show a PLAY AGAIN button. Enter or PLAY AGAIN restarts the 10-pitch game.

Build a minimal HUD over the 3D scene. At top left, show a dark translucent rounded panel with the uppercase title FENCE FINDER in light blue and the current cumulative score such as 0 FT in large white type. At top right, show PITCH 1 / 10 (updating through PITCH 10 / 10, then FINAL). Near the upper center, show large bold result messages with colors matching the outcomes: gold for HOME RUN, pale blue for DEEP FLY, coral/red for SWING AND MISS, FOUL TIP, and CALLED STRIKE; show an initial gold TIME IT RIGHT prompt when a run begins. Near the bottom center, show the instruction "Press SPACE or tap SWING when the ball crosses the gold zone" and below it a large rounded gold SWING button. Use a dark navy, teal, green, dirt-brown, gold, and coral visual palette with clean bold sans-serif typography, rounded translucent HUD panels, and a polished arcade presentation. Make the layout responsive so the canvas fills the viewport and the controls remain usable on mobile.
