Mario N.
About this gig
STOP SENDING BORING PDFs TO INVESTORS AND PLAYERS. SHOW, DON'T TELL.
A static Game Design Document (GDD) only explains your idea. A playable prototype lets people experience it. I am a rapid prototyping specialist. I will turn your core game mechanics into a fully playable, browser-based prototype in 48 hours.
Zero engines. No Unity/Unreal installs required. Pure HTML/JS/CSS.
WHAT I CAN BUILD FOR YOU:
- Interactive Combat Loops & DPS Calculators
- Drag & Drop Inventory Systems (LocalStorage saved)
- Hex Grid Pathfinding & Cellular Automata
- CSS3 3D UI (TCG Cards, Loot Boxes)
- Dynamic Tech Trees & Narrative Terminals
HOW IT WORKS:
- Send me your GDD, Notion link, or mechanic description.
- We lock the scope of a single core mechanic.
- You get a single, shareable HTML file that runs perfectly on Desktop and Mobile. You own 100% of the source code.
Message me before ordering so we can confirm the scope of your prototype! I have a live, playable portfolio with 10+ mechanics to show you.

I build interactive, browser-based game prototypes and playable pitch decks in 48 hours. No Unity, no Unreal, no downloads required. I use pure vanilla HTML, CSS3, and JavaScript to bring Game Design Documents (GDDs) to life instantly on any device.
With expertise in rapid prototyping, JS state management, algorithmic generation, and premium UI, I help indie developers, board game creators, and agencies show their vision instead of just talking about it.
Stop sending boring PDFs to investors. Send me your GDD, and let's get your core loop playable.
FAQ
Why use HTML instead of Unity or Godot?
Friction is the enemy of pitching. Investors and players do not want to download a 500MB executable, install dependencies, or wait for a heavy WebGL build to load. A single-file HTML prototype loads instantly on any device, anywhere in the world, with zero setup. It gets straight to the fun.
How does the 48-hour delivery work?
The 48-hour clock starts the moment we finalize the scope and the core mechanic to be prototyped. Due to the rapid nature of this service, it is intended for clean, specific micro-loops (Tier 2) rather than sprawling RPGs. For Tier 3, timelines are negotiated based on complexity.
Do I keep the source code?
Absolutely. You receive the complete, unminified HTML/JS/CSS file. You own the intellectual property of your game mechanics. You are free to modify, host, or dissect the code however you see fit.
