How Bill The Dev works
Four rules, for my own games and for yours.
Fast.A playable build in days, so every idea meets real hands early. Then testing on real phones until the game is right, however long that takes.
Fun.If it isn't fun as grey boxes, it doesn't get art. Feel first, polish second.
Optimize.Smooth on low-end phones and standalone VR. Profiled, not guessed.
Ease to scale.Clean systems and data-driven content, so a game or a client project grows without a rewrite.
