Origin and the role of AI
The brief, selection and art direction are mine. For the games for children, AI (Claude and Codex) wrote the code, procedural art, animation and sound based on my brief and feedback. Prototype Arena is my own Godot project; the Eduko 3D models are generated by Blender scripts written with AI.
The subject facts in the new games are checked against a source or calculated in the game's code; each game's report records which.
Open source: Phaser, three.js and Matter.js (MIT), Godot (MIT), fonts from @fontsource (OFL), ZzFX sound synthesis (MIT). Prototype Arena uses CC0 textures and sounds (ambientCG, Poly Haven, Quaternius, Kenney, OpenGameArt).
