Build an original game. Prove it is ready.

LM Game Creator is the creator-side workshop for the standalone LM Games ecosystem. Start with the repeatable core loop, use LM Assistant for ideas, story and code help, preview the concept safely, then clear originality, privacy, family, pricing and beta-review gates before anything can reach players.

Creator openness. Player isolation. No stolen ideas.LM Game Creator reviews code as text and uses a declarative sample preview; pasted creator code is not executed here. Similarity flags are review signals—not legal clearance—and unresolved red flags block beta readiness.

01 · IDEA + CORE LOOP

Define the repeatable game before expanding it.

Game titlePlayer promiseCore loopWhat will the player repeat every 5–30 seconds? Build this before adding worlds, stores, social systems, or lore.

LM Assistant prompt

GAME CONCEPT
A peaceful one-thumb space garden where players collect stars, grow glowing plants, and decorate a small world together without combat.

LM ASSISTANT BUILD PROMPT
Build this as a responsive LM Games-compatible prototype.
• Define one clear core loop and a 10-second first-play explanation.
• Support pointer/touch and keyboard controls where appropriate.
• Keep content suitable for a family-safe catalog; no gambling, sexual content, profanity, graphic violence, unmoderated chat, or hidden purchases.
• Do not embed API keys or arbitrary remote scripts.
• Pause safely when the app loses focus and clean up timers/listeners.
• Add accessible labels, keyboard navigation, and visible focus states.
• Separate game state from rendering so QA can test it.
• Include an age-rating declaration and a short parent-facing description.
Return: architecture, game loop, controls, files, then code.

02 · CODE BENCH

Write or paste the game code.

// LM Game Creator sample: a tiny family-safe tap game
const game = {
  title: "Star Catch",
  ageRating: "Everyone",
  score: 0,
  soundEnabled: false,
};

function handlePointer(event) {
  if (!event.isTrusted) return;
  game.score += 1;
  updateScore(game.score);
}

function updateScore(score) {
  const output = document.querySelector("[data-score]");
  if (output) output.textContent = String(score);
}

document.querySelector("[data-game]")
  ?.addEventListener("pointerdown", handlePointer);

03 · LM GAME BUILDER SAMPLE

Feel the loop before you publish a beta.

This preview is intentionally declarative: it does not run pasted creator code. It gives the creator a safe interaction sample while the real build remains behind review boundaries.

04 · ORIGINALITY GUARD

Originality review

Similarity detection is a creative/legal-review signal, not a legal opinion. Familiar genres and mechanics are fine to study; public work must use independently created code, names, characters, assets, dialogue, worlds and expression.

No obvious protected-name or title-similarity flag found in this lightweight review.

05 · LM READINESS REVIEW

LM Assistant recommends

Add accessible names/roles to interactive game controls.

Add keyboard equivalents so the game is not pointer-only.

Add visible focus behavior for menus and controls.

06 · LM GAMES BETA GATE

Prepare a transparent beta for LM Games.

Set the player terms, sign the creator declarations, clear originality and code blockers, then send the build to human review. LM Game Creator never treats an unchecked legal box as approval.
