The studio · what's real today

What the studio runs.

Not a product pitch — a tooling pitch. The substrate the platform runs on: a deterministic engine the games share, an AI director that reshapes live games, an AI build sandbox that ships new ones, a generator that auto-playtests a thousand levels in under fifteen seconds. The harness that runs it all.

AI Director · the kernel

Describe it. The live game changes.

A working AI director shapes a live game as you talk to it — spawn things, change worlds, behaviors, camera, audio. It calls a fixed set of constrained tools. Never rewrites code, never touches files. Every session deterministic and replays bit-identical. A constrained game director, not a code-writer.

~80 schema-constrained tools · no code-gen · deterministic · bit-identical replay
AI Build Sandbox — Bubble Pop being built end-to-end by Claude
AI Build Sandbox · the forge

Describe it. A new game appears.

Prompt → ephemeral sandbox → live preview. Daytona-style isolation, scaffold pipeline, gate-tested builds. This one is a complete Bubble Pop game built end-to-end by Claude on top of our hyper-casual scaffold. Two engines, one thesis: AI as the build surface for everything players remix.

Level generator · the playtester

A thousand levels, generated and auto-playtested, in under fifteen seconds.

Not just a solver, a real generator: batches up to 1,000 rule-aware levels, each auto-playtested 50 times by a deterministic solver, in under 15 seconds (100 in under 2). Unsolvable ones rejected, all sorted by difficulty. No human playtester. Bento today; generalizing across genres is the build.

1,000 levels generated and auto-playtested in 14.5s · 50 sims each
Leap · the platform's proof case

2D or 3D, online, with talking NPCs — one engine, one game.

A precision platformer that renders in 2D pixel-tile OR 3D from the same deterministic core — toggle live. Cheap relayed-P2P co-op for the linked-room world, with XP/progression and NPC inhabitants whose dialogue is driven by batched-Haiku live chat (validated cost-per-conversation). Cross-platform fingerprint validated 2026-06-06 across three engines. The single demo that proves the whole stack at once.

render-swappable 2D/3D · relayed-P2P co-op · live-LLM NPC chat · linked-room world · cross-platform deterministic
The engine · renderer- and physics-agnostic

One core. Many surfaces. Any device.

The deterministic core runs fully headless and ships in 2D through pixi.js and in 3D through Three.js + Rapier — Leap renders in both from the same code. Foot Brawl is 3D, Tiny Swords is 2D, Yokai Run is 3D; all on the one engine. Ships on web today; Capacitor wraps it for iOS and Android. Deterministic netcode means a phone player and a desktop player can share the same multiplayer match — frame-identical on both.

The harness · actively iterated

Voice in. Merged code out. A studio of agents.

Capture by voice or text. The harness routes to the right repo, spawns a worker in an isolated git worktree, runs QA, gates on trust tier, auto-merges or opens a PR. Overnight research agents and a librarian keep the knowledge base fresh. In active development since the start of the year — used, iterated, improved with every cycle.

An AI agent autonomously taking a turn in Urban Dead
Urban Dead · AI agents play the world

A live world where AI agents possess players.

A live SpacetimeDB world where AI agents play autonomously: explore, make first contact, fight, spend an action economy, log every turn to memory. Real and early, poll-based and bespoke. The agent behavior is the proof, not the polish.

live · SpacetimeDB · autonomous agent turns logged to memory

Founder · Sweden

Built King's first automated playtester a decade ago. Sole designer on Pepper Panic. 15+ titles shipped at Glu. Co-built Void Tyrant — a Google Play Indie Games Festival top-10 finalist (2020). Then years off the land, a degree in Japanese, and built my own agentic system before the open-source wave. Spanning design, engineering, and technical art lets me direct AI at every layer of the platform — solo since January.
