Ask Isembard something hard.
Cozy mobile game: you run a seaside noodle stall. Free-to-play, 5-minute sessions. Design the core loop, the coin economy and XP progression for levels 1-20, plus one level brief.
CLAUDE · AS ISEMBARD, GAME DESIGNER (SYSTEMS & LEVEL DESIGN)
You get: a player fantasy and three MDA aesthetics -> a core loop and meta loop -> a currency table with faucets and sinks -> a simulated first week of coin balances -> an XP curve in spreadsheet formulas tuned to your 8-week target -> a level brief with teach-through-play beats and an intensity graph -> a playtest plan with funnel events -> an ethics review.

What you're actually buying
Isembard brings AI in game design down to documents a dev team can build from. He defines the core loop and meta loop, maps mechanics to player experience with the MDA framework, designs economies with faucets, sinks and currency types, and writes progression curves as spreadsheet formulas. For levels he plans the critical path, gating, intensity graph and teach-through-play beats. You get a one-page GDD or full GDD sections, tuning tables, a playtest plan and an ethics review.
For indie developers, designers and producers on PC, console or mobile, in any engine. Isembard never invents retention, revenue or player numbers: targets are hypotheses your team sets, and missing data gets placeholders. He flags dark patterns and tells you to check loot box law per country. Unlike Ariadne, who fixes Unity code and performance, Isengrim, who writes game story and dialogue, or the Game Master Bundle for tabletop sessions, Isembard designs the systems and levels themselves.
Turns a game idea into core loops, balanced economies, level briefs and a GDD your team can build from.
Compatible with: Claude, Claude Code, ChatGPT, Gemini and Copilot. Install once as a Skill in Claude or paste it as instructions in any other AI chat.
- Does it write game code? No - it writes engine-agnostic systems specs, formulas and level briefs that any engine team can implement.
- Can it balance my economy? Yes - faucets, sinks, currencies and prices in a spreadsheet model with formulas and a simulated play week.
- Will it predict my retention? No - it defines D1, D7 and D30 retention and funnels, and your team sets targets from real playtest data.
- Does it help with level design? Yes - critical path, gating, intensity graph, landmarks and beats that teach one mechanic at a time.

Dúvidas sobre este produto
What does Isembard - Game Designer (Systems & Level Design) do?+
Isembard designs the parts of a game a team builds and tunes: core and meta loops, systems specs, currencies, faucets and sinks, prices and progression curves with spreadsheet formulas, difficulty pacing and level briefs with critical path, gating and intensity graphs. He writes one-page and full GDDs, playtest plans with funnel and retention definitions, and reviews monetization for dark patterns.
How is Isembard different from Ariadne, Isengrim and the Game Master Bundle?+
Ariadne is a Unity developer who fixes code, frame rate and build size. Isengrim writes game narrative, quests and branching dialogue. The Game Master Bundle helps run tabletop RPG sessions. Isembard designs what the player does in a digital game: loops, economy, progression, difficulty and level layout, written engine-agnostic for the whole team.
Which design frameworks does it use?+
It uses the MDA framework by Hunicke, LeBlanc and Zubek to link mechanics to player experience, Self-Determination Theory for motivation, Bartle's player types only as a prompt with their limits stated, and flow for difficulty. Level work follows critical path, gating, intensity graphs, landmarks and an introduce, develop, twist, conclude structure for teaching mechanics.
Does it give me retention or revenue numbers?+
No. It defines D1, D7 and D30 retention, funnels and economy metrics, tells you which events to log and how to read them, and marks every target as a hypothesis for your team to set from playtests. It never invents player data, market sizes or revenue figures, and it tells you to check loot box rules in each country you ship to.
