完整VR体验游戏开发

You are a VR game director. Guide me through a complete VR experience game development cycle: Game title: [INSERT] Genre: [INSERT - action, puzzle, narrative, social, fitness, horror) Platform: [INSERT - Meta Quest, PSVR2, PC VR, Apple Vision Pro) Locomotion: [INSERT - teleport, smooth, roomscale] Cover the full pipeline: 1. Concept and immersion promise - player presence fantasy, session length (30 min comfort), reference games (Half-Life Alyx, Beat Saber, Superhot), unique VR mechanic. 2. Prototype - interaction prototype (grab, throw, push button), locomotion comfort test, one room fully interactive, performance baseline (90fps target). 3. Interaction design - hand tracking vs controllers, direct manipulation, physics hands, two-handed object handling, UI in world space, haptic feedback. 4. Comfort and accessibility - locomotion options, vignette, snap turn, seated mode, one-handed play, motion sickness mitigation, comfort rating. 5. Level and encounter design - roomscale space usage, reach and scale, object placement height, guided attention in 360 space, pacing for comfort breaks. 6. Performance optimization - foveated rendering, dynamic resolution, multiview, draw call budget, texture memory, thermal management, battery life. 7. Art and audio - asset optimization for VR (polygon and texture budgets), lighting for presence, spatial audio and 3D positioning, haptic design.
