Seele AI · Focused prototype production
Build a City Eater prototype with a focused gameplay loop
Turn growing a singularity by consuming buildings, avoiding threats, and expanding across a city map into an original City Eater prototype with clear timing, feedback, and decisions.



Visible prototype result
Review the core loop before expanding content
Start with one bounded scene, one clear player goal, and a small number of meaningful interactions. Inspect controls, feedback, pacing, and consequences before scaling.

Built for early validation
Turn the brief into concrete evidence
Use growing singularity, edible buildings, roads, and escape lanes to distinguish actions, states, and consequences.
Show evacuation vehicles, defensive hazards, and collapsing structures through in-world motion and staging rather than a fake HUD.
Connect introduction, escalation, recovery, and a clear finish around growing a singularity by consuming buildings, avoiding threats, and expanding across a city map.
Independent signals
Trust is part of the build.
Two practical jobs
Test the decision that matters now

Test the central decision
Check whether players can understand growing a singularity by consuming buildings, avoiding threats, and expanding across a city map before committing to a move.

Validate escalation
Increase singularity size, target order, and city route choices while preserving a fair next action.
From prompt to next build
Shape the prototype around evidence

Compose the playable scene
Arrange growing singularity, edible buildings, roads, and escape lanes, landmarks, hazards, and open lanes for readability.

Define responsive feedback
Use animation, materials, light, motion, and sound direction to expose outcomes.

Tune session pacing
Balance singularity size, target order, and city route choices, recovery windows, failure behavior, and the target browser session.
Unity City Eater FAQ
Questions before you build
What is City Eater?
City Eater is a focused Unity browser-game prototype for testing growing a singularity by consuming buildings, avoiding threats, and expanding across a city map. A first build keeps one objective, a compact rule set, readable feedback, and a bounded play session. It is not production-ready without code review, device testing, accessibility work, asset-rights review, and human playtesting.
How do I prototype a city eater game?
Start with one playable scene and implement the smallest loop for growing a singularity by consuming buildings, avoiding threats, and expanding across a city map. Add input response, state changes, success and failure feedback, and only the progression needed to answer the first design question. Avoid expanding content until players understand the core interaction.
What should the first city eater game brief include?
Include the player goal, camera, controls, core rules, level layout, feedback, target browser, and success condition. Also define performance limits, failure behavior, accessibility needs, asset direction, and the evidence the prototype should produce. Exact implementation choices still require engineering review in the target Unity stack.
What can I test with an early city eater game build?
An early build can test input clarity, visual readability, pacing, difficulty, feedback, and whether the central decision is engaging. Keep the session short and inspect hesitation, failure, recovery, and strategy moments. Broad progression, monetization, multiplayer, and content variety should be tested separately.
What are the limits of an AI-generated city eater game?
AI can accelerate visual and interaction exploration, but it cannot prove balance, accessibility, browser performance, stability, or player enjoyment. Creators must inspect generated code and assets, profile real devices, tune values, test edge cases, and run representative playtests. Generated scenes are prototype evidence rather than a claim of production readiness.
How do I start City Eater with Seele AI?
Describe the smallest playable scene that can validate growing a singularity by consuming buildings, avoiding threats, and expanding across a city map. Name visual style, player actions, rules, hazards, feedback, objective, failure state, target device, and the decision to validate. Keep the first request narrow so revisions remain tied to the gameplay question.
