Dune Buggy Rush

Qwen AI Co-Pilot Rebuild: Vehicle physics and mid-air pitch authority re-architected with local Qwen2.5-Coder on gerp's NVIDIA GeForce RTX 2060 GPU. Restored instantaneous 360-degree mid-air GAS pitch-down control (10.8 torque / 0.108 speed cap) so pressing GAS in flight immediately arrests backward rotation and brings the nose down smoothly, while completely eliminating the unwanted backward flip on dune crests and jump ramps.

Bespoke 5-Layer Meyers Manx & Authentic Open-Cockpit Driver: Complete ground-up Argon sprite & rig rebuild modeled directly after David's burnt-copper, cream, and teal Meyers Manx dune buggy. Features a split foreground/background fiberglass body shell so David sits authentically inside the tan pleated cockpit with cap, intact mirrored sunglasses, red t-shirt, and real sunlit forearm gripping the side-profile steering wheel.

4x-Supersampled Cragar Mag Wheels & Mechanical Coilover Rig: Precision-centered 5-spoke chrome mag wheels with cross-drilled ventilated rotors spinning over non-rotating red Brembo brake calipers, paired with tubular chromoly radius arms, heim-joint bolts, and anodized piggyback nitrogen reservoir shocks.

2x Retina HiDPI Renderer & 5-Layer Biome Parallax Vistas: Native 2x devicePixelRatio rendering with volumetric dual halogen headlights, Mach shock-diamond nitro afterburners, Monument Valley flat-top mesas & saguaro dunes, blast-furnace molten slag waterfalls & sodium gantry lamps, and Cyberpunk Outrun megacity skylines.

Adaptive Biome Synth-Drive Soundtrack & Stinger Exhaust Burbles: Procedural Web Audio 16-step bassline + kick/hi-hat groove that adapts dynamically to Desert, Foundry, and Cyber-Grid biomes (toggleable via 🎵), plus air-cooled VW stinger exhaust crackle pops on throttle lift.

Live Buddy Chris Rivalry HUD & Zero-Clipping Landscape UI: Real-time HUD rivalry pill tracking your live point delta against Chris mid-run with instant celebration banner + haptics the moment you pass him, paired with safe-area-aware multi-touch pedals and zero-clipping 2-column landscape modals verified at 360px height.

Samsung Galaxy S24 & One UI 6 Compatibility Hotfix: Resolved an instant startup crash occurring on Samsung Galaxy S24 and newer One UI 6.1 devices. Migrated window insets to AndroidX WindowCompat / WindowInsetsControllerCompat to eliminate premature InsetsController lifecycle crashes on startup.

Adreno 750 & AMD Xclipse GPU Driver Stability: Removed redundant programmatic hardware layer forcing on the WebView component. Forcing explicit hardware layers conflicted with modern Snapdragon 8 Gen 3 and Exynos 2400 Vulkan rendering backends, causing GPU driver aborts on launch.

Renderer Resilience & Crash Protection: Implemented onRenderProcessGone handling to gracefully recover and reload if the underlying Chromium graphics process restarts. Added multi-process directory suffix protection and camera punch-hole cutout safe margins.

Mobile Landscape Screen Fit Optimization: Re-engineered the Game Over / Run Completed dialog into an adaptive 2-column landscape layout. Distance, Stunts, Coins, and Total Score are neatly displayed on the left, while Racer submission, the Chris rivalry card, and a thumb-friendly 2x2 action button grid fit effortlessly on the right with zero vertical clipping or off-screen button overflow on mobile screens.

Thumb-Friendly 2x2 Button Grid: Streamlined action button labels to concise, punchy touch targets ([RESUME CP], [RESTART], [🏆 SCORES], [🔄 UPDATES]) formatted into an ergonomic 2x2 grid, guaranteeing instantaneous access to checkpoints, restarts, and leaderboards without scrolling.

Fresh Start Leaderboard Reset: Completely reset the online high score database to a clean, empty slate. All initial test bots and placeholder scores have been removed so you and your buddy Chris can race on a level playing field. Local device high scores have also been reset fresh so your very first run establishes your authentic personal best!

Accurate Chris Rivalry Comparison: Fixed a mathematical discrepancy where stale local device high scores showed incorrect point differentials against Chris. The rivalry spotlight now strictly compares your actual verified personal best score on the leaderboard against Chris's best score (e.g. "🎯 CHRIS LEADS by 485 pts | Chris: 13,420 pts vs You: 12,935 pts"), matching the table below with 100% consistency.

Streamlined Landscape Leaderboard Modal: Re-architected the High Scores modal for mobile landscape screens by merging the title and racer profile into a compact top row, expanding the scrollable rankings table height by over 50%, and locking scroll position to the top so top racers (Chris and your personal best) are immediately visible without scrolling.

Personal Best Deduplication: Upgraded the leaderboard backend and client to enforce one verified personal best record per racer. Low-scoring crash runs will no longer duplicate or downgrade your standing, keeping the leaderboard clean, competitive, and uncluttered.

Full Leaderboard Modal & Racer Profile: Access the high score list anytime via the new HUD Trophy button (🏆) or post-run menus. Features customizable racer name profiles, Chris rivalry spotlight card, rankings table with medal badges (🥇, 🥈, 🥉), distance records, timestamps, and row highlights for both your score and Chris's score.

Session-Scoped Ghost Car & Fastest Run Chasing: The holographic ghost car now stays completely hidden on your very first run of each session so you can explore the track cleanly. Once your first run concludes, the ghost appears from run 2 onward and replays your fastest run. If you beat your time, the ghost immediately updates to challenge you with your new fastest run. Exiting and restarting the game cleanly resets the ghost so every session begins fresh.

High-Impulse Hydraulic Hop Physics: Upgraded the vehicle hop jump from a weak 26px upward nudge to a powerful 180px hydraulic impulse with forward momentum carry and pre-landing input buffering. The dune buggy can now easily leap over standard 60px shipping crates, ledges, rocks, and boulders from both a standstill and full speed.

Crisp Responsive SVG Hop Icon: Fixed the missing hop button icon on mobile Android devices by replacing the unsupported Unicode character with a clean, high-visibility inline vector SVG upward launch arrow.

Skill & Gameplay Challenge Restored: Fixed the issue where holding down gas allowed clearing every level automatically with zero challenge. Added authentic 2-button physics racer controls (Gas tilts nose down, Brake tilts nose up in mid-air); enabled dynamic hill-climb wheelie torque that requires active throttle feathering and driver weight leaning to avoid flipping backward; revamped Sector 1 dunes with punchy launch crests and steep landing drop-offs; and enabled solid driver head terrain collision masks so upside-down high-speed terrain slams cause fatal crashes.

True Puzzle Enforcement: The Sector 2 socket switch now strictly requires the heavy boulder, and Sector 4 requires the shipping crate—buggy tires can no longer trigger or latch puzzle gates open. The Sector 5 Cyber Laser Barrier is now powered down only by catching the mid-air boost Energy Core.

True Photo-Real Meyers Manx Dune Buggy: Replaced the old low-resolution polygon cutout with an authentic, high-resolution direct side profile extracted with neural AI background segmentation. Features the complete metallic burnt-copper body, flared front fenders with chrome rectangular headlights, tubular roll cage, windshield, beige bucket seats, and rear chrome engine cage.

Photo Driver Head 100% Visible: Completely removed the painted cartoon red cap that was covering the driver's face. The real driver head extracted from your photo sits proudly above the beige bucket seat headrest with sunglasses and baseball cap fully visible, bobbling naturally with physical g-forces and stunts.

Time-Trial Modal Mobile Hang Fixed: Fixed the victory/results modal getting stuck on landscape phones. Added dedicated ✕ close buttons, backdrop click/tap dismissal, keyboard restart keys (Space, Enter, Escape), and restructured the modal into an adaptive 2-column landscape layout so sector splits and retry buttons are never pushed off-screen.

5-Spoke Chrome American Racing Mag Wheels: Upgraded front and rear wheels to authentic chrome 5-spoke deep-dish mag wheels with knobby off-road rubber tires, matching the real vehicle's stance and rotating smoothly with 60 FPS physics.

RWD Traction Architecture (No Stoppie Lock): Ground drive propulsion is now applied strictly at the rear tire contact patch with axle-height chassis carry, creating natural rear squat on acceleration and eliminating front-wheel wheelies (stoppies) when gas is held down. The front wheel now rolls freely with only low-speed climbing assist.

Pedals Decoupled from Tilt: Gas and Brake pedals now strictly control forward drive and reverse/braking without forcing airborne tilt. Air tilt is decoupled so holding gas across jump crests no longer causes involuntary forward somersaults into the dirt.

Proportional-Derivative Flight Auto-Leveling: When holding gas in mid-air, active PD auto-leveling torque automatically stabilizes the buggy toward a clean $-0.03\text{ rad}$ (slightly nose-up) landing attitude, landing flat on all four wheels. Explicit stunt tilts (or holding brake/reverse in air) execute crisp 360° frontflips and backflips with landing speed boosts.

Vertical Normal Ground Filter: Ground contact queries now verify that collision contact normals are predominantly vertical ($|n_y| \ge 0.35$), preventing vertical barrier walls, sliding gates, and cliffs from falsely triggering grounded driving mechanics or climbing elevator bugs.

Suspension Bridge Cliff-Face Trap Fixed (512m–518m): Added overhead vertical suspender cables to every plank anchored to an overhead suspension catenary, completely preventing planks from sagging below road height under vehicle weight. Extended receiving deck with a flush 160px flat platform and added a smooth 30° under-deck ramp bevel underneath the right lip to eliminate vertical wedging traps.

Ghost Drawbridge Penetration Eliminated (1465m): Equipped the raised drawbridge with an impenetrable 260px vertical barrier body (active while raised, disarmed when lowered) that completely blocks high-speed vehicle tunneling up to 65+ MPH.

Non-Lethal Elastic Energy Barrier (1946m): Replaced the fatal instant-crash laser barrier with a debounced (600ms) elastic repulsion force: shocks vehicle backward toward the floor switch ($v_x = -25\text{ MPH}$, $v_y = -4.5$), triggers cyan/red sparks and explosion sound, and deducts $-3\text{s}$ in timed mode rather than ending the run.

Full-Stroke Hydraulic Crushers (1039m, 1133m, 1226m): Extended hydraulic piston stroke so crusher heads slam down within 0.2 car-heights ($bottomY = roadY - 48\text{px}$) of the road surface before retracting to $topY = roadY - 260\text{px}$ for clean clearance.

Mutually Exclusive Flips & Anti-Pogo Tip-Over: Flips are now queued in mid-air and strictly awarded only upon Clean/Perfect touchdown (discarded on bail), eliminating contradictory simultaneous "FLIP!" and "STUNT BAILED!" toasts. Added an Anti-Pogo Stick tip-over torque ($4.5\text{ rad/s}$) when grounded at near-vertical pitch ($70^\circ < |\theta| < 110^\circ$) at low speed (<8 MPH) to eliminate indefinite nose stands.

Stationary Flat Boulder Plateau: Sandstone boulder in Desert Sector 2 is spawned on a 240px wide flat plateau over 20 meters before the decline slope, ensuring the boulder remains completely stationary until pushed by the player.

Non-Obstructive Stunt Popups: Repositioned stunt toasts directly under the top HUD bar with a 40% smaller footprint, semi-transparent backdrop blur, and a strict 2-banner limit to preserve driving visibility.

Airborne Stunts & Clean Landing Multipliers: Full 360° backflips (+500 pts) and frontflips (+500 pts) with real-time terrain slope matching for Perfect Landings (<10°, 2x combo, 1.4x speed surge) and Clean Landings (<22°, 1.25x boost).

Roll-Cage Barrel-Roll Recovery: Curved roll-cage roof geometry with progressive rocking torque and auto-righting barrel roll when inverted. Roof impacts no longer trigger instant crashes.
