Game information

Control a kid in a red baseball cap running endlessly on three seaside railway tracks: switch lanes, jump, and slide to avoid oncoming trains, low-clearance bars, and moving blockades. Features cartoon retro 3D visuals, double scores for perfect runs, daily rewards, achievements, and local high score tracking.

"Seaside Rail Run" AI Generation Prompt

Use: Give this prompt to an AI coding assistant to reproduce the game.

Please generate a pseudo-3D three-lane infinite runner web game (third-person behind view), single file index.html, zero external dependencies (Canvas 2D perspective projection, no WebGL), logical resolution 480x854 (9:16 portrait).

1. Pseudo-3D Perspective

Physical projection: s = 6 / (6 + distance_left). Elements are scaled by projection ratio s.
Render with Painter's Algorithm (draw from far to near).
Environments: Left beach and sea, palm trees; Right sidewalks and pastel buildings; Center railway tracks with scrolling sleepers.

2. Controls & Character

PC: Arrow Left/Right to change lanes, Arrow Up / Space to jump, Arrow Down to slide, Esc/P to pause.
Mobile: Swipe gestures (threshold 34px).
Character: A cartoon kid in a red cap, white hoodie, blue jeans, and backpack. Animations for running, jumping, sliding, and crashing.

3. Balances & Hazards

Speed starts at 3.5m/s, increases by +0.4 every 15s to a max of 9m/s.
Jump duration 0.7s (max height 2.8m). Slide duration 0.6s. Lane change duration 0.2s.
Obstacles: Low blockades (jump), high-clearance overhead bars (slide), trains (change lanes), and moving blockades.

4. Score & Boosts

1 point per meter. Gold coins (+5 points) scattered along lanes.
Perfect run multiplier: dodge 10 obstacles continuously to trigger 2x score for 3 seconds.
Shield Item: Grants invulnerability and clears colliding obstacles.

5. System & Audio

Achievements, daily rewards, local scoreboards (localStorage).
BGM changes tempo based on character's speed. Sound effects for jumping, sliding, coins, and collision.
