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."
