An enemy slips past you, and one of the villagers behind you is gone. That's The Unbroken Line, the game I'm building in public with three AI systems: Claude Code writes the code, Codex reviews it, ChatGPT paints the art. I design it and sign off each Friday's build.
The prototype's battlefield: the ninja, enemies coming down the road, "VILLAGER LOST" on screen, and the villagers behind the line. The prototype's art, AI-generated with ChatGPT.

Stand in a fallen stalk's path on my game's Woodcutters' Road, and it will push you all the way back to your line. From Friday, the bamboo lies on a moving road, so it comes down the field at you. On foot, you can't cross it. When do you jump?
3
Until now, fallen bamboo in my game only ever hurt you. Field Guide, No. 10: falling bamboo, then and now. On Friday's Woodcutters' Road, it's a wall that stuns any fighter it lands on or you knock into it. What would you knock into it first?
Field Guide card No. 10, falling bamboo, then and now. Top, "Then": a bamboo circle on the ground beside the ninja. Bottom, "Now": a long stalk toppling across the road onto its dashed outline. "It used to hurt only you." Three facts: then, a circle that hurt you and never the Shadow Clan; now, a crack and a shadow, then 1.2 seconds later a stalk, hurting and stunning the fighters it lands on, and hurting you too; lying across about half the road, a wall to leap or go round, and a fighter knocked back into it is hurt and stunned.

A crack in the bamboo. A shadow falls across half the road. A moment later, so does the bamboo. That's my game's Woodcutters' Road, from Friday. Leap the fallen stalk, or run round its open end. In your way, or theirs?

Opus 5.5 is actually insane for building pixel-art indie games Stop using Midjourney for game assets, it has zero resolution awareness and instantly ruins your grid Here is the exact developer pipeline: → sketch your initial concept and pull visual references from Pinterest → ask Opus to write custom Python scripts that draw pixel-perfect art programmatically → clean up the output manually in GNU Image Manipulation or Photoshop → supply real-world motion references (like how natural creature movement works) to build a custom animation rig The real game dev workflow isn't prompt-guessing It’s a continuous loop: sketch → Opus code generation → reference correction → manual polish Precise pixels. Total programmatic control.

here’s how to solo dev polished indie games with claude opus 5.5... opus handles game logic, combat mechanics, and complex frame-by-frame animations better than any model before it the trick is structuring your codebase for rapid iteration, but there’s a smart way to set it up: - step 1: define your core game loop, state management, and combat hitboxes directly in Claude - step 2: map out character states and sprite animation frames (like sword dashes, slash arcs, and hit reactions) - step 3: script complex particle effects and crystal-shatter death animations entirely through code - step 4: let the model handle smooth animation timing and rig transitions without manual keyframe dragging - step 5: iterate rapidly on the standard $20 plan without needing a dedicated art or animation team what used to take an experienced studio team months of manual work can now be prototyped and shipped by a solo dev in weeks save this before your next game jam project ↓

Three hunters call for help just below the mist. Their countdown has already started. Field Guide, No. 9: trapped hunters. Stand beside them for two seconds and all three join you, loosing a volley as they go free. How far would you leave your line?
Field Guide card No. 9, trapped hunters: the ninja beside three hunters in a ring of rope, a gold arc showing the freeing half done. "Three hunters caught on the trail, calling for help." Three facts: two seconds beside them, in all, before their 18-second countdown ends; freed, all three join your caravan and loose an arrow volley; three groups on every run, and left too long they're taken.

The mist you'll fight in on Friday is drawn in code, a stand-in. This is the painted mist that replaces it, in a later build. New build every Friday. Build 3 available today! treyrobbinsiswrites.substack…

Hunters trapped up the road. An archer about to shoot from the bamboo. Raiders running at your line. Where do you go first? That's eight seconds of Friday's Hunters' Trail. Nobody's playing, so nobody chooses. Tell me your order.

Out today: build 3 of The Unbroken Line. You're a ninja, and every enemy that gets through your line takes a villager. The Hunters' Trail now has mist, archers hidden in the bamboo, and trapped hunters to free. How to play it: treyrobbinsiswrites.substack…

What did OpenAI just feed GPT SOL 6.1?? asked it to build a 3D axe from scratch using Blender MCP - 7 minutes total - 1% of weekly quota since when is GPT SOL 6.1 this good at 3D?

Friday's Hunters' Trail adds mist, hidden archers and trapped hunters. A bot that only runs at the enemy nearest your line still won it 15 of 15. The one-move bot, build 3: 58 wins in 60. It can't tell me if the trail is fun. You can. What would you throw at it?
A scoreboard titled "Build 3: 58 wins in 60". For each of the forest's four missions, fifteen squares across Storyteller, Guardian and Ronin difficulty. All say WON except one on the Woodcutters' Road and one on Night of the Shadow Clan, both on Ronin. Below a rule, the first mission with lessons on: one LOST, on Guardian.

Once you've seen an enemy in my game's mist, it stays seen. The first draft broke that: a strike could knock an enemy back out of sight. My AI reviewer, Codex, caught it before it merged. Claude Code fixed it, with two tests. How it's built, every Friday: link below.
A redrawn GitHub review comment from chatgpt-codex-connector on pull request #34, flagged P2: "Record sight before combat can knock enemies away." It explains that a melee hit, leap landing or Wind Wall could knock a just-revealed enemy back beyond sight before it was recorded as seen, "so an enemy the player just revealed and struck becomes concealed again."

My game's mist keeps one promise: you see every enemy at least two seconds before it can reach your line. Field Guide, No. 8: the mist. Inside it, enemies are dark shapes, and shuriken fly only at what you can see. Wait, or go in?
Field Guide card No. 8, the mist: a frame of the Hunters' Trail with grey mist over the top of the road and an archer inside it drawn as a dark silhouette. "It hides the top of the Hunters' Trail." Three facts: enemies in it are dark shapes until they come out below it or near you, and stay seen; shuriken fly only at what you can see; every enemy comes into sight at least two seconds before it can reach your line.

"The forest's hunters are cut off on the old trail." From Friday, that's where you win them. Clear the Hunters' Trail and they join your refuge: their arrow volley, and a watchtower to build. Your first win brings home the village's families. New build every Friday.
The results screen after the Hunters' Trail: "You brought them home." 30 of 30 people saved, Gold. A panel reads "A new community joins you: Hunters strengthen the refuge", with timber, iron and supplies brought home.

here’s how to build a japanese canal boat game with claude opus 5.5 + unity 6 + blender.. the trick is one system per prompt, smart way to set it up: - step 1: create a unity 6 urp project and connect opus 5.5 through unity’s plugin and blender mcp - step 2: greybox the canal: water channel, stone walls, 2 bridges, docks - step 3: boat physics: throttle, steering, wake trails, speed in knots on the hud - step 4: opus models the props in blender: the covered boat, houses, the vermilion bridge, the pagoda, lanterns - step 5: water shader + day/night cycle + rain, with lanterns that switch on at dusk - step 6: a compass on top and 9 landmarks that unlock on the map (“water gate, 3 of 9”) - step 7: docking lessons: “come alongside the temple steps below 2 kn and press e” - step 8: opus playtests in play mode, reads the console and lists bugs before fixing who does what: > blender: every model > unity 6: the water, the light, the weather, the ui > opus 5.5: boat physics, quests, scene setup, tests > you: steer it and say what feels off i like to test every feature at night in the rain. if it still looks good there, it’ll look good everywhere.

A glint in the bamboo at the road's edge. A bowstring creaks. One second later, the first arrow. Field Guide, No. 7: hidden archers, from Friday. In cover you can't see or hit them. Then they shoot until you cut them down. Go after it, or hold the line?
Field Guide card No. 7, hidden archers: the prototype's painted archer, a straw hat and drawn bow. "The Shadow Clan's archers, waiting in the bamboo." Three facts: unseen and untouchable in cover; a glint and a creak, then one second to the first arrow; then an arrow every 2.7 seconds until you cut it down, and none can touch you mid-leap.

Same mission, same eight seconds. Left: last week's build. Right: Friday's. From Friday, my game's Hunters' Trail hides things: enemies in mist, archers in the bamboo. And hunters are trapped up the road. What do you go for first?
