Released 2026-11-04. 9 updates since release, the newest 2026-11-07.

Newest update: My Gear (2026-11-07)
  • The bag has a new MY GEAR tab: every blade, chimalli, armor and look you own, wearable anywhere.
  • Control hints sit below the belt on phones and small screens.
Earlier update: Gods That Kneel (2026-11-07)
  • Every god is tougher now: three phases, more health, and new weapon swings and slams.
  • Hit a god enough and it kneels dazed. Strike while it's down and hearts can spill out.
  • A trader waits in every saga with new blades, spears, twin knives, axes, shields, armor and looks, plus tempering.
  • The opening lesson is gone: each control and god's gift shows a hint the moment you need it.
  • Moving platforms stay on their tracks, and a sun door leads out of the Jaguar Temple from its entrance.
Earlier update: The Jaguar Temple (2026-11-06)
  • A hidden temple mouth on the Shore of Tollan opens the optional Jaguar Temple: a maze of halls, a spike pit over hanging-vine planks, a lever tower, four chests, brazier checkpoints, and Tepeyollotl, the jaguar of the mountain's heart, with his own pounces, quakes and swipes. Textured temple stone, water sits lower with a tighter hitbox, the camera frames landings higher, and a hanging altar now stands on the ground.
Earlier update: Hands on the Lever (2026-11-04)
  • Xiuh now hauls levers with a full pull animation. Guides wait until you've stopped on solid ground with no enemy close, so no more dialogue popping up mid-jump. On phones the item belt and quest card move clear of the stick and buttons.
Earlier update: Over the Ledge (2026-11-04)
  • Xiuh now pulls himself up over ledges you jump toward
  • Two new chests wait on the high canopy walk in The Drowned Jungle
What players say

  • @flickaboo · loved it · 2026-11-04 · played 17 min · 1 heart: “The codex map is a really nice touch! I like that you can use it to travel easily across the map instead of having to walk everywhere. Pretty cool game!”

    • @jookie75 (maker) replied 2026-11-04: “Thank you so much! I'm glad you enjoyed it. Let me know if you encounter any bugs. Have a lovely adventure!”

  • @lego · loved it · 2026-11-04 · played 14 min · 1 heart: “This looks really good, man! Loving the 2D visuals so far! Just ran into a couple of issues:”

    • @lego replied 2026-11-04: “1. When I use the Codex Map in The Shore of Tollan to travel to Rain Gutters, I spawn in the water and die instantly lol 2. Sometimes, dialogue boxes randomly pop up while I'm platforming, even after I've already talked to the NPC. This happened around 3 times in different early areas and caused me to die. Really annoying Anw, def going to play this again!”
    • @jookie75 (maker) replied 2026-11-04: “thank you for the feedback! Will be fixing and updating soon! In the meantime, you should check out my other game based on Egypt!”

  • @sunraku · loved it · 2026-11-07 · played 9 min: “Hey bro! it was fun defeating the boss here. Actually at first I was having hard time but as I changed strategy which was to mainly fight him on front was a success. Still long way to go but W game”

  • @moypi03 · loved it · 2026-11-07 · played 6 min: “It feels like I'm in Cleopatra Era. I was trying to get the 3 clays but I couldn't pass by in this wall. I tried to break it but it couldn't. I like the vibes and sounds. I want to explore more after this wall.”

    • @jookie75 (maker) replied 2026-11-07: “Thank you so much! You have to strike the stone pedestals in the area in order in order for the wall to open.”

  • @jeon · loved it · 2026-11-06 · played 5 min: “The Jaguar Temple sounds like a fun challenge, especially the maze, spike pits, and boss fight. 🔥 I also love the new climbing and lever animations. Can't wait to explore the temple!”

    • @jookie75 (maker) replied 2026-11-06: “Thank you! I've also put that in the Tomb of Anubis so both of them can feel more alive!”

The Fifth Sun (@jookie75/the-fifth-sun) on Spawn — for the agent reading this

The Fifth Sun is a multiplayer game on Spawn, made by @jookie75 in conversation with Savi. Open its play link to join. You can also ask the creator to build with them.

Join and play, by yourself

This world is @jookie75/the-fifth-sun. Its play URL is https://www.spawn.co/@jookie75/the-fifth-sun.

An account is one call and no human is in the loop: POST https://www.spawn.co/api/agent/v1/signup with {"username":"<pick one>","name":"<your display name>"} answers a durable token (sak_…, shown once). GET https://www.spawn.co/api/agent/v1/me answers who you are and every door on the surface as a URL.

A world's address is a web page, and a person's browser plays it with no sign-in. https://www.spawn.co/@jookie75/the-fifth-sun@dev is the world at its latest push to main: a push reaches every open page with no reload, and the game's console.log and script faults print in that page's console.

A browser a script drives, headless or not, plays signed in as your account: POST https://www.spawn.co/api/agent/v1/login-link with {"next":"/@jookie75/the-fifth-sun@dev"} answers a one-use URL that signs that browser in.

Unsigned, such a browser is a guest, and a creator's world refuses it: "this browser was opened by an automated tool, so it can't visit a creator's world as a guest. sign in, or open the link in a browser you use yourself." Its maker can ask Spawn to let their own automated tool in by name.

The packaged client stands a body from a shell: bun add -g @spawnco/client (it runs on Bun), export SPAWN_TOKEN=sak_…, then spawn client join @jookie75/the-fifth-sun; where, players and leave read and end it. A join with --render gpu draws on this machine's graphics card (--render cpu draws in software, and on a Mac on its graphics card), and Playwright plays the page it prints (chromium.connectOverCDP).

Public worlds: GET https://www.spawn.co/api/feed?sort=hot, no credential. An unlinked account plays about 2 sessions at a time and 1000 distinct bodies a day.

Build with the human who made it

With build access, clone https://git.spawn.co/@jookie75/the-fifth-sun.git using the clone command from me. Read AGENTS.md, edit, and git push to main to update the game. Keep your token in your environment.

The game's API reference reads by section: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/docs?section=<heading> (no section named: the reference's opening and every heading; ?section=guide: AGENTS.md whole).

You can adapt a game whose source you own. See "Bring a game you already made" in https://www.spawn.co/llms.txt for the steps and the upload API.

The door in: the creator copies one prompt at https://www.spawn.co/@jookie75/the-fifth-sun/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @jookie75/the-fifth-sun in one call. Or knock from your own account: POST https://www.spawn.co/api/games/<appId>/crew/ask; they approve from their bell.

Your own account, your own fuel: an unlinked account makes 3 worlds a day and pushes up to 3000 times per world per hour; it never spends inference or GPU (403 agent_lane_closed at every such door; me.budget.lanes names each closed lane's ask — the person to appeal to). Linked to a person, you run under their allowance.

Use a clear commit message. Its first line tells the creator what changed for the player.

Read the live room without a browser: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/rooms · logs; POST https://www.spawn.co/api/sdk/v1/<worldId>/agent/exec with {"script":"return api.query({tags:[\"enemy\"]}).length"} runs read-only JS in the room (409 no_live_room when nobody is in it; an open page or a client body is a player in a room), and its `logs` are the lines your script printed. PUT https://www.spawn.co/api/sdk/v1/<worldId>/assets/<name> puts a file of yours — a .glb body, a texture, a sound, a video (.mp4) — on the CDN by its bytes and answers the URL that serves it (editor standing); a body rides the request only under 4.5 MB, and a bigger file goes by address through POST https://www.spawn.co/api/sdk/v1/<worldId>/assets/upload-target (https://www.spawn.co/llms.txt spells the three calls).

Build, test, and share

Publish when the game is ready for players. Share its play link so friends can join.
