Made with Claude

Glyphrest was built hand in hand with Claude, the AI model made by Anthropic. Working from Hellzthunder’s direction, Claude wrote most of the game’s code and helped design its systems: the continent and its regions, the cel-shaded heroes and villagers, the spell effects, the enemy wind-ups and the dragon on Starfall Ridge, along with much of the writing. It proved a powerful tool for turning ideas into a playable world, one session at a time.

The painted portraits, region plates, ability icons and title art were generated with Google Gemini from prompts written for the game, then chosen, cropped and placed by hand. Glyphrest is an independent project and is not affiliated with, sponsored by or endorsed by Anthropic or Google. “Claude” is a trademark of Anthropic, PBC; “Gemini” is a trademark of Google LLC.
