Opus 5.5 Game Creator Agent
Can you make the game you actually want to play? Yes. Start by describing the repeated player action, world, rules, device, session length, audience, and one original feature. The creator workflow organizes mechanics, controls, level structure, feedback, and revision into a browser-ready plan.
Step-by-step
Use the agent as a design and implementation partner. Keep each step observable so you can decide whether the game improved.
Use this pattern: “The player repeatedly ___ so that ___ while ___ becomes harder.” Example: “The player rotates a tiny moon base to catch drifting repair drones while solar wind changes their paths.”
Give the round a finish line. State what creates score or progress, what ends the attempt, what persists, and whether the next round should begin instantly or return to a menu.
Name portrait or landscape, touch or pointer, keyboard or gamepad, and the minimum supported screen. Explain whether one hand, two hands, shared keyboard, or a microphone is expected.
State how the player recognizes a valid move, damage, score, danger, cooldown, objective change, and failure. Sound and animation should support visible information rather than hide it.
Ask for a single polished level or endless loop. Avoid adding accounts, stores, multiplayer, procedural worlds, and a long story before movement, score, failure, reset, and performance work.
Open the prototype as a new player. Check whether the interface explains itself. Try wrong actions, repeated clicks, a small screen, lost focus, muted audio, and a restart after failure.
Replace “make it better” with evidence: “the first enemy arrives before controls are understood,” or “the touch button overlaps the score at 390 pixels.” Ask for alternatives and compare them.
Review licenses, rights, privacy, dependencies, analytics, hosting, accessibility, error handling, and security. Remove keys from client code, compress media, and test the deployed build.
Prompt blueprints
“Create a portrait touch puzzle where players slide colored radio signals through a six-by-eight storm map. Each move advances the storm. A round lasts under three minutes, supports undo, and has high-contrast symbols in addition to color.”
“Create a keyboard-and-mouse arena game where a courier redirects enemy projectiles with a magnetic shield. Use WASD, pointer aim, one primary action, ninety-second rounds, readable cooldowns, and instant restart.”
“Create a detective game where players interview a ship AI aloud. Score relevant questions rather than accent. Show recording state, provide text fallback, allow deletion, and make low-confidence speech recoverable without ending the case.”
“Keep the current core movement and art direction. Replace the confusing inventory with three visible slots, delay the first timed objective by twenty seconds, add keyboard focus guidance, and make a failed round restart in one action.”
Playable references
The 600-game list helps you compare feedback, pace, controls, and restart behavior. The Choicer Voicer AI game is a strong reference for timed voice performance, microphone states, and a generated result. Use references to describe quality and constraints, not to copy protected code, characters, art, or levels.
Creator questions
The strongest workflow begins with a constrained, complete loop. Describe the player action, rules, controls, result, and target device, generate a first prototype plan, test it, and then expand. One oversized prompt is less reliable than deliberate iteration.
Yes. Explain what must remain, what feels wrong, and the measurable change you want. Use only code, assets, characters, and references you are allowed to edit.
Test whether a new player can identify the objective, controls, feedback, win or failure state, and restart without reading your original prompt. Then test mobile layout, focus, performance, and error recovery.
Yes. Define microphone permission, recording state, retry behavior, scoring rule, privacy, failure recovery, and what speech changes in the game. Choicer Voicer is linked as a playable voice-game reference.
