A one-man game studio in Ho Chi Minh City, run by Bill.

Shades on.Ship it.

I make my own games, and I build Unity, web and AI projects for studios and businesses. The same pair of hands from the first grey-box build to the store page.

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.

Need it built? Hire the dev behind the games.

Games, web, AI and tech art for studios and businesses. You work with the person who writes the code, from the first call to the handover.
