Gas Escape

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 3D arcade game titled “Gas Escape.” The player controls a small cartoon fart/gas bubble trying to travel through and escape a squishy human digestive-body tunnel. Use Three.js-style rendering with a dark burgundy background and fog, a winding Catmull-Rom tube tunnel extending forward from the throat toward an exit, and a glossy pink/red interior with a soft lighter inner glow. The camera follows just behind and slightly above the player, looking forward down the tunnel; the player is a round lime-green translucent bubble with a subtle emissive glow, gentle pulsing scale animation, two tiny dark eyes, and a worried open curved mouth. Movement is radial within the tunnel cross-section while forward travel happens automatically over time: use WASD or arrow keys on desktop, and on touch devices show a large translucent circular joystick in the lower-left with a bright green draggable knob. Clamp the bubble to stay inside the tunnel, and apply smooth movement/damping.

Make each run last 15 seconds. The player moves from the throat through named route stages shown in the HUD: Throat, Windpipe, Belly Tube, Stomach, Intestines, and finally Exit!. Display a fixed white HUD over the game: “Gas Escape” at top-left; top-right shows remaining Time counting down from 15.0, Score, and the current route name plus Health. Under the top bar, show a rounded horizontal progress bar spanning most of the screen, filled with a green-to-yellow-to-orange gradient according to travel progress. Initially show a centered/lower instruction panel saying: “Dodge the acid blobs. Arrow keys / WASD, or drag the green thumbstick.” On touch layouts move this hint upward to avoid the joystick.

Populate the winding tunnel procedurally for each run with approximately 22 bright green acid blobs placed at different forward positions and radial locations. They should be irregular faceted/icosahedron-like blobs with occasional small dangling drips, glow slightly, wobble around their radial angle, and rotate. When the player reaches an obstacle’s forward position, detect close contact: hide the blob, flash the dark background red briefly, play a short harsh sound, and subtract one health. Start with Health 3. If health reaches zero, reset health to 3, move the bubble back toward the tunnel center, rewind about 2.2 seconds of progress, and subtract 100 points without ending the run. Also place approximately 14 collectible yellow snack bubbles along the route as small rotating torus-knot shapes, with floating motion. If the player is close when passing their forward position, hide the snack and add 25 points with a short cheerful beep. Add about seven faint pink glowing checkpoint rings across the tunnel, with gently pulsing opacity.

The player should have a headlamp/point light near the camera, warm ambient lighting, and a bright greenish light at the far exit. The route should visibly curve and sway, and the tunnel should feel organic and squishy rather than architectural. When 15 seconds elapse, pause the action and show a centered dark translucent rounded modal titled “Fresh Air!” with text reporting the run number, escape time, and score, followed by a simple randomized cartoon man card: blue sky/green ground background, a stylized man assembled from a randomly selected skin tone, shirt color, pants color, and hair color, with a slight random hair tilt, plus a small animated pale-green fart cloud beside him. Include a bright green pill-shaped “Escape Again” button. Clicking/tapping it, or pressing Space/Enter after finishing, starts a new run with score and health reset and a newly procedurally varied obstacle/snack course and man card. Add simple synthesized sounds for collecting, collisions, restart, and completion, but keep gameplay fully playable without requiring sound.
