GHOST CITADEL
Ghost Citadel builds Linux-first games for Steam Deck, PinePhone, desktop and browsers. Every project starts on real hardware, under real limits — then climbs up from there.
This page is the living roster of what’s on our workbench: flagship titles, experiments and browser builds on their way into the Playground.
A Pallas cat battles for freedom against a ruthless rat underworld in a sprawling, atmospheric Moscow. You navigate back alleys, rail yards and frozen riverbanks while avoiding surveillance and using improvised tools to escape the city piece by piece.
Built for Steam Deck and desktop Linux, with a WASM subset planned for Playground. Tight controller support, dense telemetry and a focus on stealth, routes and emergent escapes rather than combat.
A Lapland lane-racer where reindeer, icy curves and northern lights replace cars, asphalt and city noise. Originally built as a physics testbed, Reindeer Racer evolved into a full arcade project focused on readable tracks, rubberbanding that feels fair and clean, and rock-solid 60 FPS on modest hardware.
Designed to run on Steam Deck, Linux laptops and eventually browser builds via WebAssembly. Built with strict telemetry: every lap, drift and collision feeds back into better AI and difficulty tuning.
A dune-and-pier chase along the Curonian Spit: sprinting cats, shifting sand, Baltic wind and seagull-infested shortcuts. Nida Beach Cats is about momentum and risk–reward — do you cut across unstable dunes or play it safe along the boardwalk?
Targeted at phones, Steam Deck and Linux handhelds, with a strong focus on readable silhouettes, battery-friendly rendering and short, replayable runs.
A neon air hockey arena built as a control and latency experiment — zero camera fuss, pure input-to-motion. Vector Rink tests how far we can push responsiveness on Linux, Steam Deck and browser builds while still looking sharp.
Under the hood it is our sandbox for hit detection, prediction and rollback experiments. On the surface, it’s a dangerously competitive couch game.
A grid-based chase game inspired by arcade classics, rebuilt with modern pathfinding and telemetry. Formerly nicknamed “Catpac”, Cat-Runner focuses on ghost AI behaviour, cornering, prediction and making every chase feel just barely survivable.
Used internally to test BFS pathfields, corner-cut assistance and behaviour logging. Planned targets include PinePhone, Steam Deck and a Playground build with live heatmaps.
Boom is our take on the bomber-style arena: tight levels, chain reactions and fast rounds built to be watched as much as played. This project started as a remake and is now a test case for cleaner code, deterministic replays and better AI opponents.
Boom is also one of our first candidates for a public Playground build: short matches, minimal UI, and strong value as a performance and stability benchmark across devices.
Many of these titles will have small, self-contained scenarios available in the Playground: no save data, no accounts — just pure, replayable slices that run in a modern browser.
Steam Deck, PinePhone Pro and ARM-based Linux machines are our primary targets. Other platforms follow once the game feels great on the hardware we care most about.
