찰싹 한판

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.

Recreate a mobile-first Korean arcade tapping game titled "찰싹 한판" (roughly "One Slap Round") as a single-screen web game. Use a warm, playful pastel visual style: the full viewport has a diagonal gradient background from pale pink to pale yellow, with a centered responsive app column no wider than about 620px. The header contains the bold Korean title "찰싹 한판" on the left and two rounded white statistic cards on the right: score labeled "점수" and remaining time labeled "초". Start every round immediately with score 0 and a 20-second countdown.

The central play area is a large rounded rectangular arena with a soft cream/pink radial gradient, a subtle dark translucent border, inner pink bottom shading, and a drop shadow. Center one large circular face button in the arena. The button should be about 76vw wide up to 350px, circular, peach-colored (#ffd0a7), with a thick offset bottom shadow in darker peach and a soft outer shadow; it sits slightly raised. By default show a large shocked-face emoji "😳" centered inside it, with a translucent white shine ellipse near its upper-left. The button must also support a user photo: below the title, display helper text "사진을 올리고 얼굴을 눌러보세요"; provide a Korean upload control labeled "📷 사진 넣기" accepting image/*, and when an image is selected, use it as a circular object-cover face image and hide the default emoji. Keep the shine overlay visible.

Core gameplay: the player repeatedly taps/clicks the circular face button. Handle pointer/touch presses immediately (and also allow the Space key as an alternative slap). Each valid slap during the active 20-second round adds 10 points plus a combo bonus. A combo increments when the previous slap happened less than 850 milliseconds ago; otherwise it resets to 1. Cap the combo bonus at 5, so rapid consecutive hits award 11, 12, 13, 14, then 15 points per hit (and continue at the capped bonus while hits remain rapid). Update the score card after every hit. Do not accept hits after the timer reaches zero.

On each slap, animate the face button briefly down and slightly smaller/rotated (about -2 degrees), with a brighter/more saturated appearance, then return it to its raised position. Also show large comic Korean text "찰싹!" above the face, colored hot pink/red with a white and dark outline, popping in, enlarging, then floating upward and fading out. Spawn exactly eight small colorful circular particles at the press location inside the arena. Use a palette including pink, yellow, cyan, pale green, and orange; scatter them outward/upward with random horizontal and vertical offsets, rotation, shrink, and fade over roughly 0.55–0.6 seconds. The effect should work at the actual pointer location, not only at the center.

The round lasts exactly 20 seconds using a one-second countdown. When time reaches zero, stop the timer and disable further scoring, then display a translucent dark blurred overlay over the arena with a centered cream rounded modal. The modal says "끝!", shows the final score as "[score]점이에요", and has a full-width pink button labeled "다시 하기". Pressing it resets score, combo, timer to 20, active state, and hides the modal. Also include a yellow rounded "↻ 리셋" button in the bottom controls that performs the same reset immediately. The controls sit below the arena in one row: the upload button is white and flexible/wide, while reset is yellow. Add the small centered hint text "얼굴을 빠르게 많이 누르면 콤보 점수가 올라가요" below the controls.

Make the layout responsive for portrait mobile screens, with large touch targets, rounded corners, strong soft offset shadows, and no scrolling. On short screens reduce padding/gaps and hide the helper and hint text while retaining the game. Use Korean text exactly as specified, system sans-serif typography, and preserve the cheerful sticker-like look visible in the reference: simple geometry, pastel gradients, bold dark-purple text, and tactile press animations.
