Behind the Build | Div Zero

01 Hardware

Comfort Is Design. So Is Play Time.

Div Zero is shorter than most puzzle games. That is not a limitation. It is a decision made deliberately because of the hardware it runs on. Vision Pro is worn. Fatigue is real. Every minute of unnecessary length is a minute of physical cost, and padding a spatial experience to match PC game expectations would have been the wrong call.

"The session length is not a constraint we worked around. It is part of the design itself."

Discovery loops were shortened. Unnecessary friction was removed. Puzzle structures were re-evaluated not just for elegance but for physical cost. The result is a tightly paced experience that respects both the player's time and the reality of what they are wearing.

02 Interaction

Touch Without a Controller

One of the most interesting challenges in building for Vision Pro is touch. The display is sharp enough, and the blend of AR and VR convincing enough, that the usual tricks stop working fast. You cannot hand the player a controller. You cannot fake physical interaction when their hand passes through empty air.

"The world looks virtual, but touch still connects to something real."

One sequence in Div Zero places the player inside a virtual scene that visually transforms their real room into something else. The player still sees their real hands, and the physical space is still there beneath the illusion. That creates a strange and powerful effect: the world looks virtual, but touch still connects to something real.

03 Presence

Finding the Line

Vision Pro sits at the edge of two worlds, and staying on the wrong side of that line costs everything. Too much AR and the experience stops feeling transported. Too little and you lose what makes the hardware special: the feeling that your room is no longer just your room.

A significant portion of development went into calibrating that balance. Transitions between mixed reality and full immersion had to feel intentional rather than accidental. Every state change needed to read as a choice, not a glitch. The player has to trust that the world is doing something on purpose.

04 Subtraction

Everything That Got Cut

Every added layer risked pulling the player out. UI, tutorials, music, pacing: all went through repeated rounds of reduction. The question at every stage was not whether something was good but whether the experience was better with it than without it. Usually, it was not.

"Black fades looked less cinematic and more like the system had stopped working."

Even transitions required careful decisions. Softer tones maintained continuity where hard cuts broke it. What remains is only what presence actually needed, and the discipline to stop there.

05 Platform

Building the Template

Beyond development, one of the challenges of building for Vision Pro is that you are also helping define what players expect from the platform. Discoverability, market size, and premium positioning are all still evolving. There is no established playbook for what a native spatial experience should feel like. Only what has been ported from elsewhere.

"The game is not only trying to entertain. It is also trying to show what native spatial can be."

That makes design decisions carry extra weight. Div Zero is a deliberate, polished experience built around presence, atmosphere, and trust in the medium. Built for this hardware, not adapted to it.
