A single-player real-time strategy game built with Three.js featuring a techno-magical post-apocalyptic setting where you lead a specialized expedition team through the dangerous wasteland to discover ancient artifacts.
Note on sound at http://ieve.me/manifest ... it actually works in the game, although I should compress these WAV files into something not so huge. But I lost the battle against nginx, who just... will not serve the dang wav files.
In Manifest, you command a small squad of specialized units including a precision Neon Assassin sniper and a resilient Scrap Golem as they navigate through a desolate techno-arcane wasteland. Your mission is to reach and secure ancient beacons while avoiding or confronting hostile forces that guard this forgotten realm.
The game code was 99+% generated by LLM AI's in Mar 2025, mostly Claude 3.7 Sonnet, Claude Code, Gemini Thinking 2.0, and Manus (which I think is just using Claude underneath?) I, the human, integrated the generated code in, complained about bugs, and felt very helpless while I let Claude Code chooch on a 'vibe-specification' (that is, a specification that was also 'vibe coded').
Game was written for the 2025 Vibe Game Jam
- Tactical Combat: Command specialized units with unique abilities like the Neon Assassin's precision sniping
- Dynamic Fog of War: Explore and reveal the mysterious wasteland as you progress
- One single semi-janky but technically working mission: Alright I gotta go to work now...
The game is built with a modern, component-based architecture:
- Entities are just IDs in the game world
- Components are pure data structures attached to entities (position, health, faction, etc.)
- Systems contain game logic that operates on entities with specific components
