Blitzdown

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 arcade football running game titled “Blitzdown,” using a dark, polished Three.js-style presentation and a mostly top-down, slightly angled follow camera. The camera should look down the length of a rectangular green American-football field, with the player starting near the near end at the bottom of the screen and running toward a gold-colored end zone at the far end. Use a deep navy background with atmospheric fog, soft shadows, warm directional lighting, cool rim lighting, and a restrained low-poly/stylized look.

The field is a broad green rectangular surface with alternating darker/lighter horizontal turf stripes, white yard lines across the width at regular intervals, short hash marks, and white boundary lines. Put a gold end-zone rectangle across the far end, with small white markings inside it. Add dark block-like spectator stands along both sidelines, with repeated blue seats on the left and red seats on the right.

The controllable avatar is a simple stylized quarterback/running player centered on the field: a pale blue-white capsule-like body, an orange rounded football helmet, and a dark visor. Start the player at the near end of the field and let the player run freely left/right and forward/backward within the field boundaries using WASD or arrow keys. The camera follows the player in a top-down view. On touch/mobile, provide a virtual movement control/joystick consistent with the visible circular control at the lower-right of the screen. The player carries a small blue ball that follows near the player’s front/side and visibly rotates while moving.

Place six simple opposing defenders downfield. They should be low-poly red-bodied capsule figures with light cream heads/helmets. Their positions should form a staggered obstacle course: approximately (-5,12), (5,7), (-3,-1), (4,-8), (-6,-15), and (5,-20) relative to the field, with each defender oscillating horizontally around its base position. If a defender comes within roughly 1.15 world units of the player, tackle the player unless the player is currently juking. Make Space trigger a short juke window (about one third of a second), visually shifting the carried ball slightly to the side; the juke lets the player avoid a tackle during that brief period.

Implement a four-down football drive. Begin with 1st & 10, 0 points, and a 30-second play clock. Track yards gained on each play based on how far the player has advanced toward the far end. If the player gains at least 10 yards on a play, display a first-down message, reset the player to the starting position, and give a new 1st down. If tackled for fewer than 10 yards, reset the player and advance from 1st to 2nd to 3rd to 4th down, showing a tackle/status message. If tackled on fourth down without reaching the first down, end the game with “Turnover on Downs.” If the 30-second clock expires, end with “Drive Clock Expired.” If the player reaches the gold end zone/far goal line, award 6 points and end with “Touchdown!” and a message that the player broke the plane for six points.

The HUD should be a fixed translucent dark glass interface over the game. At top left, show the brand “BLITZDOWN” in small spaced gold lettering, then a prominent down-and-distance readout such as “1ST & 10,” plus “0 PTS” and a countdown such as “30s.” At top right, show a translucent status panel with concise guidance such as “Press Start Drive, then run through the defense,” and update it during play with movement/tackle/first-down feedback. At the bottom left, show a translucent legend reading “WASD / arrows to run · Space to juke · reach the gold end zone” on larger screens. Use rounded panels, subtle borders, backdrop blur, and a dark navy overlay aesthetic.

On initial load, pause gameplay and show a centered modal card over a radial dark blue overlay. The card should say “Blitzdown,” explain that it is a fresh four-down football challenge and instructs the player to pick up the first down, survive the defense, and reach the gold end zone, with a prominent orange “Start Drive” button. When the drive ends, show a similar centered modal with the outcome title, explanatory text, and a “Restart Game” button. Support Enter to start/restart when not running, and Space for juke. Keep the experience focused on running, dodging, downs, clock management, and reaching the end zone; do not add passing, teams, or unrelated gameplay systems.
