LEPOR: Foundry Pit

Newest update: The Regent Ascends (2026-09-13)

• The Regent now towers over the arena as a towering final boss, no longer a distant threat.
• Face a completely redesigned boss arena with new environmental hazards and destructible structures.
• The Regent's attacks have been rebuilt from the ground up — adapt your tactics or fall.

Earlier update: The Verdant Update (2026-09-12)

• 35 new trees now grow across the foundry landscape—poplars line the western trails while oaks cluster near the eastern lake.
• The world feels less barren. Trees frame the paths and clearings, giving the pit a sense of place and age.
• Existing structures were carefully preserved as the forest took root—the foundry's bones remain untouched.

Earlier update: The Grove Awakens (2026-09-12)

• Three new shelterbelts of organized trees have grown across the foundry lands, creating natural gathering points and windbreaks throughout the world.
• Trails now wind through carefully planted groves—the northwest, northeast, and east lake regions have been reforested with trees scaled to feel organic and lived-in.

Earlier update: The Descent (2026-09-12)

• The foundry pit has collapsed inward — the arena floor now sits 76 units deeper than before, fundamentally reshaping the stage geometry.

Earlier update: Debug Forge (2026-09-12)

• Creators can now toggle a live debug panel during arena runs to inspect motion, abilities, and real-time game state.
• The debug panel displays your mecha-rabbit's velocity, grounding state, jump timing, and active combat stats — all sampled live at 250ms intervals.
• Debug access is owner-only and fully audited across mobile and desktop layouts — no gameplay changes, no exploits.

What players say

• @makeriffic · 2026-09-12 · played 27 min · 1 heart: “Yo, I am digging the character models in this game, the bulwark guardian and skimmer enemies look sick, but I haven't got to the boss I have only managed to defeat until round 11. Maybe you can add some upgrades to help reach the boss?”

• @lego · 2026-09-12 · played 18 min · 1 heart: “you're cooking up another mech rabbit game? looking forward to it dude! i hope u can make the attacks look much clearer and cooler this time”

• @parz1val · 2026-09-20 · played 20 min: “Dude, this game is soooo good! The movement is really smooth, and I love using the dash while damaging enemies. My strat takes some time, but I actually enjoy it lol. I do hope you add some kind of attack animation or indicator though, since right now I’m mostly just relying on the cooldowns to know when I can attack again. Overall, brother, I really love the game!”

• @larrielabs · 2026-09-13 · played 7 min: “Awesome game! The movement feels so smooth! 🏃‍♂️💨 I also love the skills, especially the dash... I mostly used it because it feels so satisfying to zoom around! 😂✨ Would be nice if the enemies had a little knockout animation when you defeat them! 👀✨”

• @mistarpudding · 2026-09-12 · played 56 min: “its amazing how you made the quadrupedal movement of the rabbit so smooth! really love the mech design you're going with. i enjoyed looking at the mech more than anything. the pulse attack doesnt seem to have any visual effects, so i kind of struggled on fighting with it.”

  • @mistarpudding replied 2026-09-12: “i dont think the animations for the attacks are showing other than the one where you're just idle. i tried attacking while jumping, and attacking while running but there is no animation”
  • @mistarpudding replied 2026-09-12: “i could see the animations now after the new build! but they are very subtle and hard to see, but still, great that it finally has animations! keep going!”

Join and play, by yourself

This world is @makepix829/lepor-foundry-pit. Its play URL is https://www.spawn.co/@makepix829/lepor-foundry-pit.

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 that any browser plays, headless included, with no sign-in. https://www.spawn.co/@makepix829/lepor-foundry-pit@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.

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 @makepix829/lepor-foundry-pit; 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/@makepix829/lepor-foundry-pit.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/@makepix829/lepor-foundry-pit/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @makepix829/lepor-foundry-pit 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 — 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).
