Slingshot Smash

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 physics demolition game titled “Slingshot Smash,” using a Three.js-style WebGL scene with a fixed third-person perspective aimed at a construction yard. The camera is a perspective camera positioned above and behind the player at approximately (0, 7.8, 18), looking toward the stacked blocks around y=3; use soft shadows, fog, ambient hemisphere lighting, a warm directional sun, and a subtle teal rim light. The scene should have a dark blue/teal background wall and a broad concrete foundation/platform, with a stylized low-poly construction-yard set dressing: scaffold posts and diagonal braces at the left and right edges, wooden scaffold planks, vertical metal pipes, strapped wooden crates, a yellow warning sign with dark diagonal stripes, and a row of small safety bollards. Use a polished, colorful but industrial visual style with rounded game UI, muted navy, cream, amber, cyan, coral, wood brown, brick red, dark steel, and translucent turquoise glass materials.

The core interaction is a slingshot demolition puzzle. At the foreground center, place a reinforced wooden slingshot with a dark grip, two angled wooden forks, metal collars, dark rubber bands, and a pale ball in a pouch. The player presses/touches the pouch, drags it backward mostly in the x/y plane, and releases to fire. Limit the pull distance to about 3.35 units and prevent dragging upward; show the rubber bands stretching between the pouch and fork tips. While dragging, show a dotted amber trajectory preview and fill a horizontal power meter at the bottom from cyan through amber to coral. A pull shorter than about 0.22 does not fire. On release, consume one shot and launch a ball forward into the yard with velocity proportional to the pull (roughly 4.3 times the pull vector); the pouch disappears until another shot is available. Balls are affected by gravity, spin as they fly, collide with blocks, bounce/reverse with reduced velocity, and disappear after hitting the ground, leaving the play area, or roughly eight seconds.

Build the first level as a stack of nine construction blocks on the center platform, with four shots available. The stack has three rows: bottom row four wide blocks at x=-3,-1,1,3; middle row three blocks at x=-2,0,2; and top row two blocks at x=-1,1. Each block is approximately 2 wide, 1 high, and 0.9 deep, with the rows at y=0, 1.1, and 2.2. Alternate colorful materials among wood, brick, metal, and translucent glass. Give wood blocks dark horizontal grain slats, metal blocks amber bolt details, glass blocks dark metal edging, and brick blocks horizontal mortar lines. Also include a second level named “CROSSBEAM DEPOT,” with four shots and a wider, denser 13-block stack: five 1.5-wide blocks on the bottom at x=-3.4,-1.7,0,1.7,3.4; four on the next row at x=-2.55,-.85,.85,2.55; three on the next row at x=-1.7,0,1.7; and one top block at x=0, using the same varied materials.

Blocks should be physical dynamic objects: gravity pulls them down, they can be pushed and rotated by impacts, settle on the foundation or on other blocks, and fall away when knocked off the structure. Detect ball/block overlap in x/y/z, award a hit only once per ball per block, flash the impacted block white, reverse/dampen the ball velocity, and apply an impulse and angular rotation to the block. Each successful hit increases the combo and awards 100 multiplied by the new combo value. Spawn a burst of colorful tetrahedral fragments, dust spheres, and an expanding amber ring at each impact, with a short camera shake. When all blocks have fallen, show “YARD CLEARED · PERFECT DEMOLITION,” award a 500-point completion bonus, and reveal a “Next level” button. If all shots are spent and all balls are gone while blocks remain, show “Out of shots — reset and try again.” After firing, update the hint to “Aim for the weak point” during aiming, then “Line up the next shot” if shots remain or “No shots left — finish the chain” otherwise.

Overlay a responsive HUD above the 3D scene. At the top-left show a dark translucent brand panel with “SLINGSHOT SMASH” and the current level label, initially “LEVEL 01 · BOARDWALK YARD.” At the top-right show three light cream statistic pills labeled SHOTS, SCORE, and COMBO, initially 4, 0, and x1. Center a rounded dark hint pill near the top reading “Drag the pouch back to fire.” At the bottom center show the outlined power bar. Put Reset and, when unlocked, Next level buttons at the bottom-right (on narrow screens they may span the lower edges). Use pointer/touch controls with pointer capture, prevent page scrolling, and keep the interface usable on mobile.

On initial load, show a centered dark translucent overlay over the yard with a rounded card. The card should be labeled “CONSTRUCTION YARD // 01,” title “MAKE IT FALL,” explain: “Pull back the reinforced sling, line up the weak point, and turn the whole yard into a combo.” and provide a prominent amber “Start demolition” button. Starting or resetting loads the current level, resets its shots and combo, clears balls/effects, and hides the overlay. The overall experience should feel like a compact tactile arcade physics puzzle focused on limited shots, chain reactions, score multipliers, and knocking down the entire colorful construction stack.
