Stillwater

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 calm, minimalist 3D fishing game titled “Stillwater.” Use a Three.js-style low-poly outdoor scene viewed from a fixed elevated three-quarter perspective, with the camera looking across a wooden dock toward a quiet lake at sunset. The scene should fill the screen and use soft atmospheric fog, warm peach/orange sky lighting, gentle blue-green fill light, shadows, and a stylized low-poly nature aesthetic.

Scene composition: create a broad circular muted green shoreline/ground and a large semi-transparent blue-green circular lake surface behind and beyond the dock. Put a rectangular brown wooden dock in the foreground, extending away from the camera toward the water, with visible pale narrow slats/gaps running lengthwise across it, four dark wooden support posts underneath, and a simple brown bench near the far end. Place a warm glowing setting sun low in the distant background. Scatter low-poly oak trees, bushes, and clumps of grass around the shoreline; the visible style should be faceted and simplified rather than realistic. The dock is the focal point, with the water and sunset taking up the middle/background of the view.

Add a simple fishing rod leaning diagonally upward from the dock, with a thin pale fishing line extending from its tip down into the lake. The bobber is initially hidden. At the end of the line, when cast, show a small red bobber with a small gold/yellow tip floating on the water. Also show very subtle pale circular ripple rings around the bobber area. Animate the lake with only slight slow vertical and rotational movement, animate the ripple group gently, and keep the overall mood quiet and contemplative. The camera should remain essentially fixed, with only an extremely subtle idle sway.

Gameplay is a single-button timing loop. Start in an idle state with the status text “The lake is calm. Cast your line.” and a button labeled “Cast line.” When the player taps/clicks the button, enter a waiting state: show the bobber and line, disable the button, change its label to “Waiting…”, and display “A line drifts on the water…”. Wait a random interval of about 1.8 to 4.3 seconds. Then enter the bite state: make the bobber visibly bob up and down rapidly, enable the button, change its label to “Reel in!”, and display “A bite! Tap reel!”. The player must tap the button during this bite state to catch a fish. On a successful reel, hide the bobber and tip, return to idle, enable the button with the label “Cast again,” display a message in the form “You caught a [18–64] cm sunfish. Nice and easy.”, increment the fish count by one, and add that randomly selected whole-number fish length in centimeters to the total centimeter score. If the button is tapped while waiting, do nothing; tapping it in the bite state reels in immediately. There are no enemies, hazards, movement controls, lives, missed-catch penalty, or other gameplay systems.

Overlay a responsive, touch-friendly HUD over the 3D scene. At the upper left, use a translucent dark blue-gray rounded card with a subtle border/shadow and the title “STILLWATER” in bold uppercase lettering, plus the subtitle “A quiet evening by the lake.” At the upper right, use a matching translucent rounded stats card showing two counters: the current fish count and the cumulative length in cm, with warm pale-yellow large numbers and the labels “fish” and “cm.” At the bottom center, show the current status message, then a large rounded pale-yellow/orange button with dark bold text, then the hint “Tap the button when the bobber splashes.” Keep the UI legible over the sunset and water, with a soft shadow behind the status text. The design should work on both desktop and mobile, use pointer/touch input, and avoid any extra menus or screens.
