Leaf Crown

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 "Leaf Crown" as a single-player, touch-friendly royal-battle card game with a dark casino/VHS presentation. Use a full-screen near-black navy background and a Three.js-style velvet casino table in the background: a broad deep-blue circular table/disc low in the scene, four faint concentric gold scoring rings, and sparse floating gold dust particles. Add a subtle fixed VHS overlay with horizontal scanlines, faint RGB/chromatic offsets, a moving tracking sweep, and mild glitch color treatment, while keeping the HTML/UI crisp and readable.

Layout: use a fixed HUD over the background. At the top-left show the gold, bold title "LEAF CROWN". At the top-right show rounded dark statistic pills: "Score" with the current score, "Deck" with remaining deck count, "Discard" with discard count, and "Royal" with the number of royals remaining including the active royal. Center the main play area on the active enemy card. The enemy is a large portrait-oriented playing-card panel, roughly 250px wide on desktop and responsive on mobile, with a pale gold border, rounded corners, dashed inner border, soft shadow, glow, and animated diagonal card glint. Its background depends on rank: Jack blue/purple, Queen pink/purple, King red/orange. Display the rank at upper-left, suit symbol at lower-right, and a stylized CSS portrait in the center: halo, crown, face, eyes, hair, and colored royal body. Queens have dark/gold hair and pink/purple clothing; kings have brown hair and orange/red clothing; jacks have dark hair and cyan/blue clothing.

Under the enemy card show rounded tags for "Health", "Attack", "Shield", and "Combo x" with live values. Below that show a horizontal combo meter with a dark rounded track and a green-to-yellow-to-pink fill. Below the meter show centered status text explaining the current state, such as "New run. Beat every royal and chase leaf combos for score.", attack/defense instructions, defeat messages, or win/loss messages.

At the bottom, show a selected-card information bar. When cards are selected, display tags for selected count, total value out of 10, detected combo name, and score preview; when none are selected display "Tap cards to select. Value must be 10 or less to attack." Below it place buttons: gold "Play Hand", lavender "Discard Selected", lavender "Rules", and pink/red "New Run". Buttons are chunky, rounded, high contrast, with a pressed-down effect and disabled styling. At the very bottom show the hand as a horizontally scrollable row of eight large, slightly tilted, tactile cards. Cards are cream/white with gold-white borders and shadows; odd/even cards tilt in opposite directions, and a selected card lifts upward, enlarges slightly, gets a bright yellow outline, and loses its tilt. Each card shows a large rank, centered suit symbol, and a small bottom-right suit-power label. Hearts and diamonds use red text; clubs/spades use dark text; leaves use a vivid pale-green-to-green gradient and dark green text; jokers use a luminous green/purple wild-card treatment. Queen and king hand cards use a small illustrated CSS portrait instead of plain center rank content, and jokers use a colorful clown-like CSS face.

Game setup and data: construct a shuffled deck containing every rank A through 10 in five suits—hearts, diamonds, clubs, spades, and leaves—plus exactly two leaf joker wild cards (50 numbered cards plus two jokers). Number values are A=1 through 10=10; jokers have value 0, suit leaves, and count as wild combo cards. Draw up to an 8-card hand. Construct and shuffle 12 royals: Jack, Queen, and King for each of the four non-leaf suits. Jacks have 20 HP and 10 attack, Queens 30 HP and 15 attack, Kings 40 HP and 20 attack. The active royal is removed from the shuffled royal queue one at a time; after all are defeated, end in a win state and say "You took the Leaf Crown! Final score ...".

Core interaction: tapping/clicking a hand card toggles its selection. A selected hand may be played only when its total numeric value is 10 or less, it is nonempty, the run is not over, and the game is not waiting for defense. The Play Hand button (and Enter key) attacks the active royal. Base damage is the selected cards' value sum. If at least one selected card is a club, double the base damage by adding another base amount. If at least one is a spade, add the base value to the player's shield. If at least one is a diamond, draw cards equal to the base value, limited by the 8-card hand cap and remaining deck. If at least one is a heart, move up to base-value cards from the discard pile back into the deck (shuffle those recovered cards before placing them back). Played cards leave the hand and go to discard.

After an attack, if the royal survives, incoming damage is max(0, royal attack minus current shield). If incoming damage is positive, enter defense mode and require the player to select and discard cards whose total value covers the incoming amount; update the message with the remaining defense needed. The Discard Selected button discards selected cards and subtracts their total from the defense requirement. Once fully covered, draw back up to eight and return to the player's turn. If not defending, Discard Selected simply discards the chosen cards, draws back to eight, and cools the combo meter by 6. A non-defense discard is allowed to cycle unwanted cards. If a royal is blocked completely by shield, let the player play again and draw back up. Preserve the actual shield behavior: shield is increased by spade plays and displayed, but the implementation does not subtract shield after absorbing an attack. If the player has no cards left in both hand and deck while needing defense, lose the run.

Combo/scoring system: analyze selected cards. Ignore jokers when collecting ordinary ranks, but include them in combo size and use their count to cover gaps in runs. Recognize, in priority order, Four Kind (multiplier 3.4, +25 meter), Full House (3.0, +22), Royal Run when a run is also a flush (3.2, +24), Triple (2.2, +16), Run (2.0, +14), Flush (1.8, +12), Pair (1.45, +8), otherwise High Card (1). A run requires at least three cards, distinct ordinary ranks, and total gaps no greater than joker count. A flush requires at least three cards and all non-leaf suits matching; leaf cards do not prevent it. Each leaf card adds 12 meter; two or more leaves prefix the name with "Leaf " and add 0.45 multiplier per leaf plus 10 meter, while one leaf adds "+ Leaf" and 0.25 multiplier. One joker prefixes "Joker "; two prefix "Double Joker "; each adds 0.9 multiplier and 22 meter. If the selected cards contain all five suit IDs, call it "Five-Suit Bloom", add 1.4 multiplier and 28 meter. Compute combo chips as round(max(1, selected value sum) * 8 * combo multiplier * current combo multiplier). Add chips plus damage*5 to score; display a floating gold/pink combo text such as "Pair +...". Increase combo meter by the combo's meter, capped at 100. Current combo multiplier is 1 + floor(combo meter / 25)*0.25. When a royal is defeated, add royal max HP*15 to score, cool meter by 18, update multiplier, announce the defeat, advance to the next royal, and refill the hand. Clear selection after actions.

Include a Rules modal opened by the Rules button, with a dark purple panel, gold border, scrollable explanatory text, and close-on-button or backdrop click. Support keyboard shortcuts: Enter plays the selected hand, D discards selected cards, and R starts a new run. New Run rebuilds and shuffles the 52-card deck, resets discard/score/shield/combo/defense/win-loss state, creates the shuffled royal queue, draws eight cards, and starts with a fresh Jack/Queen/King enemy. Use responsive sizing so the enemy and cards remain usable on phones, with the hand horizontally scrollable and no page scrolling.
