A 2D endless runner browser game starring Slipping Jimmy, who must dodge obstacles while sprinting through the streets. Built with pure HTML5 Canvas, CSS, and vanilla JavaScript — no frameworks, no dependencies.

Open index.html in a modern browser (Chrome recommended) and start running.

Voice mode uses your microphone for movement — select it in the menu before starting. No voice data is stored.

Each level gets progressively faster with more frequent and dangerous obstacles.

• 📁 Case Files — Stacks of legal documents sliding across the ground
• 🔨 Hammer (Gavel) — Fast-moving judge's gavel
• 🔫 Gun — Fires bullets at Jimmy. Both the gun and its bullets are lethal

• Two Control Modes — Keyboard or Voice (microphone-based) with a mode selector in the menu
• Dash Mechanic — Press Space for a brief burst of invincibility with afterimage trail effects
• Phone Collectible — Rare phone pickups spawn in lanes. Grab one for +500 bonus points and a "Better Call Saul!" animation with signal wave effects
• Screen Shake — Canvas shakes on death for impact feedback
• Day/Night Theme — Toggle between a dark city night and a bright daytime look
• Music & SFX — Menu song, two in-game tracks (auto-rotate), and per-obstacle collision sounds. Mute/unmute pauses and resumes without restarting
• Context-Aware Catchphrases — Jimmy says different things depending on performance: confident when doing well, frustrated after multiple deaths, and milestone callouts at score thresholds
• Speech Bubbles — Follow Jimmy as he moves between lanes
• Particle System — Dust trails, hit particles, dash burst, confetti on level completion, and sparkle effects on phone pickup
• Parallax Scrolling — Multi-layer seamless city background with buildings and windows
• Progress Bar — Visual progress toward the target score at the bottom of the screen
• High Scores — Per-difficulty high scores saved to localStorage
• Loading Screen — Preloads all audio and sprite assets with a progress bar
