별똥별 피하기

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 full-screen 2D vertical space-dodging arcade game titled “별똥별 피하기” (Avoid Shooting Stars), rendered on a responsive HTML canvas with a dark navy-to-purple vertical gradient background. Scatter about 90 small softly glowing cream/yellow points across the background as stars; they drift slowly downward and recycle from the top when they leave the screen. Keep a fixed HUD over the canvas: at the top left, show a rounded translucent dark pill containing a yellow star icon and the score, initially 0; at the top right, show a matching pill with a red heart and 3 lives. Use Korean UI text.

The player is a small glowing cyan triangular spaceship near the bottom center of the screen. Draw it as a broad upward-pointing triangular ship with wing-like lower corners and a small white circular cockpit/light near its upper center, with a cyan glow. Move it horizontally only, using ArrowLeft/ArrowRight or A/D on desktop. Clamp its center roughly 30 pixels from either screen edge. Also provide two large translucent rounded-square mobile buttons at the lower left, labeled ◀ and ▶; holding either button continuously moves the ship in that direction, and release stops it. Display a lower-right Korean hint: “키보드: ← → 또는 A D” on one line and “모바일: 아래 버튼을 꾹 누르세요” below it.

The game begins with a centered modal card over the playfield: a rounded dark blue translucent gradient panel with a subtle light border and shadow. Show the large title “별똥별 피하기”, the instruction “작은 우주선을 움직여 별을 모으고, 떨어지는 운석을 피하세요!”, and a yellow rounded button labeled “출발하기”. The button has a darker gold bottom shadow and a pressed visual state. Starting or restarting resets score to 0, lives to 3, clears all falling objects, centers the ship, and hides the modal. Enter/Space should also start when the game is not running.

During play, continuously spawn falling objects at random horizontal positions just above the top edge. About 28% are collectible yellow five-point stars, radius about 10, with a bright yellow glow; collecting one removes it and adds 10 points. The other objects are irregular lavender-gray rocks/meteors, radius roughly 13–26, with a purple glow and a darker crater detail; they fall faster than collectibles. Falling speed should increase slightly over elapsed time, and spawn intervals should tighten over time but never become shorter than about 0.22 seconds (starting around 0.72 seconds). Objects that pass below the screen are removed. Award passive score continuously at about 2 points per second in addition to collected-star points, and display the integer score.

Use simple overlap collision between the ship and each falling object. Hitting a rock costs one heart, removes the rock, and gives the ship about 1.2 seconds of invulnerability with a visible blinking/flickering ship effect. If all three lives are lost, stop the game and show the centered modal again with title “게임 오버”, subtitle formatted as “최종 점수 X점! 다시 도전해서 기록을 깨보세요.” using the final integer score, and button text “다시 하기”. Keep the same HUD and controls visible. Do not add shooting, enemies beyond the falling rocks, vertical movement, power-ups, sound, levels, or other mechanics not described. Use a clean neon-glow arcade aesthetic, rounded glassy HUD panels, and Korean typography matching the supplied visual style.
