The Challenge: From 15 Years of Design to Game Development

I’ve spent over 15 years as a Graphic Designer. I always wanted to build my own game, but coding felt like an impossible wall to climb. Everyone told me I needed a team and years of study.

I decided to prove them wrong. Using Flutter and AI tools, I built and published my first mobile game, Inheritance Simulator, in just 15 days.

The Tech Stack

Framework: Flutter (for cross-platform performance)
Logic & Coding: Assisted by AI (to bridge the gap in my coding knowledge)
Design: My 15 years of expertise + AI-enhanced assets

The Game Concept: High Stakes & Brutal Reality

I didn't want to make another "happy" life sim. In my game, you start with a $3,000,000 inherited debt.

Beggar to Tycoon: You start with nothing.
Risk vs. Reward: Choose between a slow legal career or the high-risk 'Underworld'.
Consequences: One bad heist can lead to prison, just like in real life.

Key Learnings as a Solo Dev

Building this as a solo dev taught me that the barrier to entry in game development has been shattered by AI. It’s no longer just about knowing every syntax; it’s about problem-solving and vision.

I’m constantly refining the 'debt' mechanics and adding new life events. I’d love to hear from this community: How are you integrating AI into your development workflow?

I'm open to all technical feedback and collaboration!
