How to prompt

Write the fantasy, the loop, and one constraint. Skip lore dumps.

The reasoner rewards specificity about verbs, not adjectives.

Good:

"A jungle survivor sprints from zombies. Stamina drains. Safe rooms close after 20 seconds."

"A tycoon where each dropper costs more and the base expands along a path."

"An obby. Checkpoints. Platforms fall after you leave them."

Weak:

"Make a really cool game."

"Like Fortnite but better."

A three-page lore bible with no verbs.

Mention HUD only if it is part of the loop (ammo, timer, cash). Mention monetization only if you actually want it in v1 — the reasoner will skip shops unless you insist.

Iteration prompts should name the system: "The stamina bar never drains" is better than "fix it."
