Last Seen Online - v0.1

You've recovered a corrupted messenger archive from an abandoned computer. It contains a late-night conversation between two users—one of whom may no longer be… entirely present.

Navigate a retro Windows XP-style desktop, make choices that deepen the mystery, and watch as the interface itself begins to glitch, corrupt, and respond to your presence. With atmospheric audio, CRT visual effects, and a story that escalates from casual chat to digital unease, Last Seen: Online blends nostalgic UI design with psychological horror.

Features:
• Fully interactive messenger simulation
• Progressive visual/audio corruption system
• Retro desktop environment with authentic XP-era styling
• Dynamic typing indicators, notifications, and status effects
• Tab-title psychological trickery
• Optimized for dark rooms and headphones 🎧

Built with vanilla HTML/CSS/JS. No frameworks. Just atmosphere.
