Credits & licenses

A little game, made with a lot of heart.

The game

Published by Matt Salinas. Inspired by ideas developed together with Ivan. Game development, procedural effects, original interface artwork, and writing were created with AI-assisted development tools. Some arena and fallback illustrations were generated with OpenAI image tools. The playable 3D characters are artist-made models.

For Ivan, a promise made is a promise kept! Enjoy your game!
