About the developer
Hi, I’m Zachary.
Solo developer · West Virginia
PolyPixel Interactive is the name behind my independent game development work.
I’m Zachary, a solo game developer based in West Virginia. I’m the creator of Black Hollow, Mulligan Mayhem, and Plague Doctor: Apothecary.
My projects explore different kinds of play: surviving a dark-fantasy world, taking on an undead golf course, and making remedies in a small-town shop. I take a hands-on approach to development, shaping each game around its own setting, mechanics, and character.
