Mountain Rush

# Gameplay Design and Flow ## Core Gameplay Loop The player starts with a basic vehicle and enters an endless procedurally generated map. The objective is to drive as far as possible while collecting coins, fuel, gems, and power-ups. Every meter traveled increases the score. The player must carefully balance speed, fuel consumption, and vehicle stability. The terrain continuously changes with hills, valleys, bridges, ramps, rocks, and obstacles, making every run unique. The player can perform front flips, back flips, long jumps, and wheelies to earn bonus coins and combo multipliers. At the end of each run, collected rewards are used to upgrade the vehicle, unlock new vehicles, purchase cosmetic items, and access new maps. Stronger vehicles allow players to travel farther and complete more difficult missions. This gameplay loop should create an addictive "one more run" experience. --- # Complete Gameplay Flow Launch Game ↓ Animated Splash Screen ↓ Main Menu ↓ Daily Reward Popup ↓ Select Vehicle ↓ Select Map ↓ Start Game ↓ Countdown (3, 2, 1, GO) ↓ Drive Across Endless Terrain ↓ Collect Coins ↓ Collect Fuel ↓ Avoid Obstacles ↓ Perform Tricks ↓ Complete Missions ↓ Unlock Achievements ↓ Vehicle Runs Out of Fuel OR Crashes ↓ Game Over Screen ↓ Show Statistics ↓ Award Coins and XP ↓ Upgrade Vehicle ↓ Play Again --- # Driving Controls Accelerator button on the bottom right. Brake button on the bottom left. Optional tilt buttons for controlling vehicle rotation in the air. Support touch controls, keyboard controls, and gamepad controls. Controls should feel responsive with no noticeable delay. --- # Driving Mechanics The vehicle should respond naturally to slopes. Acceleration should depend on engine power. Braking should feel realistic. Suspension should absorb impacts. Vehicle weight affects climbing ability. Steeper hills require more power. Large jumps require momentum. Landing badly can damage the vehicle. Driving backwards is allowed. Rolling downhill increases speed naturally. --- # Terrain Gameplay Terrain should never repeat exactly. Generate smooth curves. Generate steep mountains. Generate deep valleys. Generate broken bridges. Generate tunnels. Generate ramps. Generate caves. Generate cliffs. Generate narrow roads. Generate dangerous downhill sections. Generate long climbs. Randomize terrain every game. Every map should feel different. --- # Vehicle Physics Gameplay The player must balance the vehicle while driving. If the front wheel rises too much, the vehicle can flip backward. If the front wheel lands too hard, the vehicle may flip forward. Wheel grip changes depending on terrain. Vehicle suspension compresses during landing. The heavier the vehicle, the harder it is to rotate. Vehicle upgrades should noticeably improve driving performance. --- # Fuel Gameplay Fuel slowly decreases during driving. Steep hills consume more fuel. Boost consumes additional fuel. Fuel cans appear throughout the map. Missing multiple fuel pickups creates tension. Low fuel warning begins at 20%. Fuel indicator flashes red when nearly empty. If fuel reaches zero, the vehicle slowly stops and the game ends. --- # Coin Gameplay Coins appear in multiple patterns. Straight lines. Arches. Vertical stacks. Hidden caves. Above ramps. On dangerous cliffs. Inside tunnels. Large golden coin clusters reward risky driving. Coin magnets automatically collect nearby coins. --- # Trick System Players earn bonus rewards by performing tricks. Front Flip Back Flip Double Flip Triple Flip Long Jump High Jump Wheelie Stoppie Perfect Landing Air Time Near Crash Recovery Long Drift Combo Tricks Each trick awards bonus coins, XP, and combo points. Display stylish popups like: Perfect Flip Huge Jump Epic Landing Awesome Combo Legendary Trick --- # Combo System Performing multiple tricks without crashing builds a combo multiplier. Example Front Flip * Wheelie * Perfect Landing = 3x Combo Higher combos increase coin rewards and XP. Combo resets after crashing. --- # Obstacle Gameplay The player encounters dynamic obstacles such as: Rolling rocks Moving logs Falling trees Broken bridges Swinging hammers Explosive barrels Spikes Mud pits Ice patches Oil spills Water crossings Lava pools Each obstacle requires different driving strategies. --- # Power Up Gameplay Magnet automatically attracts nearby coins. Turbo gives temporary speed boost. Shield protects against one crash. Repair Kit restores vehicle health. Double Coins doubles collected coins. Unlimited Fuel temporarily stops fuel consumption. Low Gravity allows massive jumps. Extra Grip improves traction. Power-ups have limited durations with countdown timers. --- # Mission Gameplay Every run includes active missions. Examples: Drive 1000 meters. Collect 200 coins. Perform two backflips. Travel without flipping. Collect five fuel cans. Reach maximum speed. Drive on one wheel for five seconds. Finish without taking damage. Complete all daily missions for bonus rewards. --- # Dynamic Difficulty As distance increases: Terrain becomes steeper. Obstacles become more frequent. Fuel pickups become rarer. Coin rewards increase. Vehicle speed naturally increases. Special events begin appearing. This keeps gameplay exciting and challenging. --- # Boss Events Every few thousand meters, trigger special challenge sections. Rockslide Avalanche Sandstorm Volcano Eruption Meteor Shower Earthquake Bridge Collapse The player must survive these events for large rewards. --- # Random Events Treasure Chest Coin Rain Mystery Tunnel Abandoned Mine Hidden Shortcut Rainbow Bridge Secret Cave Lucky Spin Portal Flying Balloon carrying bonus coins These events encourage exploration. --- # Game Over Conditions Fuel reaches zero. Vehicle flips upside down for more than three seconds. Vehicle health reaches zero. Player falls into deep water or lava. Player drives outside the map boundary. --- # Game Over Screen Display: Distance Traveled Highest Speed Coins Collected Gems Collected XP Earned Tricks Performed Longest Jump Longest Wheelie Longest Air Time Mission Progress Achievements Unlocked Best Score Play Again Upgrade Vehicle Return to Garage Watch Rewarded Ad to Continue --- # Progression Each completed run earns: Coins XP Gems Achievement Progress Mission Progress Season Progress Player Level Unlock Tokens As players level up, they unlock: New Vehicles New Maps Vehicle Parts Paint Colors Exclusive Wheels Character Skins Background Music Weather Effects Special Trails Premium Challenges --- # Goal The gameplay should be simple to learn within 30 seconds but offer enough depth through physics, upgrades, missions, tricks, progression, and procedural environments to keep players engaged for hundreds of hours.
