VR Phobia: Birds
A gentle, graded exposure experience for Meta Quest. Start with a single sparrow at the far end of a quiet park and move closer only when you are ready, all the way to a bird resting on your open hand.
VR Phobia is a prototype for adults, ideally used with the support of a professional. Its clinical effectiveness has not been evaluated; it is neither a diagnosis nor a medical treatment.

SpaceSim: Pale Blue Dot
A single-player space simulation that brings together rocket building, spaceflight and astronomy. Your journey starts with a small test rocket. What you learn and deliver opens the way to larger vehicles, orbital infrastructure and distant destinations.
The studio's engine
SimEngine
The open-source game engine built for LLMs, not for mouse clicks.
A lean C++20 and Vulkan engine with no editor. Coding agents build, run and verify the game from the terminal, with seeded runs, captures and proof for every change. Alpha, free under the MIT license, public with the first release.
