Kellian's Comic Shop
All 14 adventures in full colour. Turn the pages online, or download the A4 comics to print and keep.
Kellian's World
A live multiplayer 3D world in your browser. Claim a plot, sculpt terrain, generate AI textures, play retro arcades and explore virtual high streets.
Kellian Hide & Seek
Ready or not! Find six friends hiding around Kirk Sandall. Explore Headingley Close, cross the railway bridge by the Glasshouse, and search Lancaster Avenue and the shops — all in one connected 3D neighbourhood. Walk up to a friend to find them and watch them run home.
Kellian Infinite
An endless adventure across every location on Earth. Every stone doorway leads to a different country and a completely different game. Start in a back garden in Doncaster, then step through to Giza to colour in a pyramid while a mummy chases you — or to Paris, where an enormous pigeon has your chips at the top of the Eiffel Tower.
🚧 Being built one country at a time — expect new doorways to keep appearing for a long while yet.
Kellian Bounce
Breakout, rebuilt in a back garden in Doncaster. The trampoline on the lawn is your bat, Kellian is the ball, and the wall hangs in the sky above the washing line. Six gardens across six villages — and every landing gives the pets a fright.
Kellian Maze
A 3D cartoon chase through Doncaster town centre. Clear the precinct of butterscotch with four of them on your tail — past the market stalls and the clock tower, and out under the railway arches to the other side of the board.
Kellian Four
Connect Four on a giant board wedged in a cartoon canyon. Pick a column and Kellian sprints off his ledge, leaps into the gorge and flattens into a counter mid-air before sliding into the slot — the computer just drops an ordinary one.
Kellian: Cow Invasion
The town centre is overrun. Run the streets and spring off awnings, buses and bridges to squash the herd, chaining combos for a rising multiplier — while charging bulls launch you clean across the road.
Kellian Jump
Bounce up an endless tower of platforms in 3D. Climb from the meadow through the clouds and out past the Kármán line into deep space — if you can keep landing.
Kellian Crossing
Hop across endless roads, rivers and railways as Kellian. A more 3D take on the classic — swing the camera around, zoom in, and see how far you can get.
Kellian Rush
A 3D speed adventure through Sunbreak Coast, Canopy Ruins and Afterlight City. Boost, drift and grind rails with Kellian, find hidden shards and chase your best time.
Kellian Run
An endless runner tearing through the streets of Doncaster. Dodge roadworks, vault barriers and slide under danger to own the streets.
Other Experiments
Galaga 3D
The 1981 arcade machine, emulated from scratch and then pulled into three dimensions. Every lit pixel becomes an extruded block and the black background falls away entirely, so you can orbit the whole game, drop it onto a neon grid or seal it inside a glass case.
Build A Bot
A modular contraption lab. Drag parts onto the plate to engineer your own robot, then test-drive it and send it into battle.
Kellian's Dressing Room
Upload a photo and try on hundreds of fancy-dress outfits — superheroes, fantasy, animals and more. Save your favourite looks.
Kellian Photo Fun
Snap a photo with your camera and turn it into playful, effect-packed creations. Needs a camera, so it's best on your phone.
Kellian Point 3D
A live 3D compass that points you toward any place you search, using your phone's GPS and motion sensors.
1985: The Living Room
Walk around a mid-eighties front room built entirely out of code — no textures, no models, every surface drawn the moment the page loads. The television works: it is running an NES emulator written from scratch, 6502 and all. Sit down on the carpet, pick up the pad, or drop in one of your own cartridges.
