Gary from IT did something unspeakable to the mainframe. Now every firewall is a dungeon, every process is a monster, and you, an underpaid contractor, have been voluntold to fix it.
Neon Depths is a turn-based, cyberpunk roguelike rendered in high-fidelity ASCII art. No installs, no save-scumming, no survivors. Play it right in your browser or grab the desktop build.
Bump an enemy to enter the Neural Overlay, a modal combat screen where you pick from five directives:
Each one has a distinct behaviour pattern. The Maintenance Shell heals itself if you slow down. The Asset Drone is fragile but explodes on death. The Auditor chips away at your attack power with every hit. The Phantom phases through a third of your attacks. There are five more. The Executive shows up every three floors with two phases and no patience.
The Middle Manager is thick-skinned and slow. The Unpaid Intern has almost no HP but levels up 40% faster than anyone else. The Consultant hits hard, has no defence whatsoever, and starts with a Disruption Invoice. The Legacy Code was deployed in 1987 and cannot be removed; it begins with Technical Debt and is entirely undocumented.
Loot drops across three rarity tiers: weapons, armour, consumables, accessories. Between floors there are corporate contract briefings, redacted incident reports, and encrypted memos that do nothing for gameplay and everything for atmosphere.
There is no final floor. Enemy stats and loot quality scale continuously. The game ends when you do.
The whole thing runs on HTML5 Canvas with audio synthesised in real-time via the Web Audio API. No sprite sheets, no external libraries. Procedural maps with field-of-view lighting. It's about 3,500 lines of vanilla JavaScript.
This was my first real project using agentic AI for development. I wanted to see if I could replicate the spirit of the Seven Day Roguelike Challenge and it was insanely fun. Had it up and running in five days.
