City Dash

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 2D browser arcade endless runner titled “City Dash,” shown in a centered responsive game panel with a dark navy UI. Use a 900x600 canvas with a 3:2 aspect ratio. The player is a stylized cartoon runner centered near the bottom of the play area on one of three fixed vertical lanes at x positions 300, 450, and 600. Draw the character as a small human figure: dark blue rectangular torso with a cyan glow/shadow, peach circular face, black hair, yellow belt/shirt detail, pale eyes, and dark blue legs. Give the character a subtle up-and-down running bob.

The playfield is a vertically scrolling three-lane road. Fill the center from x=200 to x=700 with charcoal gray asphalt, slightly lighter gray side borders around x=210 and x=682, and two dashed pale-yellow lane dividers at x=375 and x=525. The divider dashes scroll downward continuously to communicate forward motion. Keep dark charcoal side margins outside the road. Behind and around the road, draw a simple bright city landscape: a cyan-to-pale sky gradient, rows of blue-gray blocky buildings along both sides with repeating small yellow windows, a green horizon/grass strip around y=350, and a green ground gradient toward the bottom. Use clean, colorful, flat cartoon vector shapes with soft glow effects on the character and coins.

During play, spawn red motorcycles/bikes from the top in random lanes. They move downward toward the player at the current road speed. Draw each bike as a red vertical body, dark wheels above and below, a yellow headlight/detail, and a peach rider head. The player must switch lanes to avoid bikes; collision ends the run immediately. Spawn bright gold coins independently in random lanes, moving downward slightly slower than bikes. Animate each coin with a rotating/pulsing effect, a golden glow, a pale outline, and a visible dollar-sign mark. Collect a coin when it is close to the player in the same lane, remove it, increment Coins by 1, and add 25 score points. If a bike passes below the player without a collision, add 10 score points once. Gradually increase the forward speed over time, and make bike spawn intervals become shorter with a lower bound, while coin spawns occur roughly every 0.55–1.05 seconds.

Controls: on desktop, ArrowLeft/ArrowRight or A/D shift the player one lane left or right, clamped to the three lanes. On mobile, provide two large tap buttons labeled with left and right arrows beneath the canvas; tapping shifts one lane. Include a start overlay before play and a game-over overlay after collision. The start overlay should say “City Dash,” explain in Hindi/English-mixed text that the character should move left and right to collect bright coins and avoid oncoming bikes, and have a button labeled “Run start karo.” On game over, show the Hindi-styled message “Bike se bach gaye!” with the final score and coin count and a replay button labeled “Dobara run karo.”

Surround the canvas with a responsive dark navy interface: header title “CITY DASH,” a subtitle about collecting character coins and avoiding bikes, pill-shaped counters “Coins 0” and “Score 0,” and a footer showing desktop controls “A/D ya ←/→” and mobile instructions. Use rounded borders, blue outlines, subtle shadows, a dark translucent blurred overlay, and a gold primary button. Keep the game continuously animated with requestAnimationFrame-style updates, and expose no extra mechanics such as health, weapons, power-ups, or multiple stages.
