Game development plugin for Hermes Agent: audio, sprites, 3D models, engine pipelines and a playtester

What Hermes GameForge does

GameForge adds a set of tools to Hermes Agent for making games. Its tools cover sound effects with 22 presets, music rendered as a loop WAV and MIDI, NPC voices, sprite sheets, tilesets, low-poly 3D models exported as .glb, engine pipelines for web, Godot 4, Unity, Blender and Unreal, a playtester and an exporter. The web engine builds an HTML5 game across four genres: topdown, platformer, arena and roguelike.

The playtester plays the build in headless Chrome using an explorer, a monkey or a vision-LLM agent, or bot-plays Godot at 40 times real time, and reports crashes, stuck spots, FPS, boredom and a heatmap. Export targets include a PWA bundle, an itch.io zip, single-file HTML and Capacitor Android and iOS wrappers. The README says everything runs offline with pure Python and Pillow, which Hermes already ships. Providers such as fal.ai, Meshy, ElevenLabs, Edge TTS and your Hermes TTS are opt-in. It is a standard plugin.yaml plugin and touches nothing in Hermes core. Ten bundled skills teach the workflows.
