GRAB — Night Shift

Develop a browser-based horror claw machine game named GRAB — Night Shift, fully powered by WebGL and structured within a mobile-first core framework. Core gameplay flow: first present a virtual coin insertion entry prompt to users, then implement on-screen touch control modules that let players precisely manipulate the claw's horizontal and vertical movement, set the claw to drop when users trigger a confirmed tap action, and design the game scene as a worn-out late-night arcade cabinet with hidden prizes placed inside the cabinet space. Add a pre-triggered jumpscare mechanism that activates under specific timing and condition rules, with dark, tense scene atmosphere as the core presentation foundation. 

For underlying technical implementation, build core game logic based on Three.js for 3D rendering and Cannon.js for physical simulation, package the core game as a classic script runtime, and embed it into a Next.js/React application shell that has been specifically optimized for Eazo mobile device compatibility and performance. Required feature set cover: real-time physics simulation for all in-cabinet prizes to ensure natural movement and collision effects, complete mobile touch control logic supporting claw movement and drop operations, atmospheric audio and visual effect modules that adapt to game rhythm, the built-in jumpscare trigger and presentation module, as well as a moody monochrome horror-style HUD interface with retro monospace typography to unify the overall horror aesthetic. Ensure the entire game runs smoothly on mainstream mobile browsers, with no obvious lag or compatibility issues.
