I developed Alepou and let Codex build a playable VR game for Quest 3 — end to end

Hi — I’ve been building Alepou, an open-source workspace for long-running coding-agent projects, and I used this Quest 3 project as a fairly extreme test of it.

It’s a small 1990s-inspired point-and-click adventure in VR. Codex 5.6 Sol did the actual build work: researching the period objects, modelling them in Blender, creating LODs, assembling the Unity scene, and implementing the VR interactions, UI, inventory and game logic. It also worked against the triangle/rendering/lighting budgets I’d set for a 72fps Quest 3 target.

I worked with Codex on the planning, then it broke that into hundreds of tasks and could keep working through them for long stretches without me having to feed it the next prompt.

I recorded quite a lot of the process and put together a 3:40 walkthrough here:

The thing I’ve been building around this is Alepou. The basic idea is that the project owns the plans, tasks, transcripts and history rather than all of that living inside one AI conversation. It also gives the agent direct bridges into Blender and Unity.

Alepou isn’t released yet, but it will be free and open source. I’ve put a bit more about it here if anyone’s interested:

Mostly interested in what other Quest developers make of this — particularly the asset/LOD/performance side of letting an agent work across the whole project rather than just generating code.
