FAQ
My game works on my PC but breaks on other browsers can you fix that?
Yes. Browser compatibility is one of my core specialties. I test across Chrome, Firefox, Safari, and Edge to find exactly where your HTML5 game breaks and why.
What if you can't fix the issue?
I review every project before accepting. If the issue is outside scope, I'll tell you before you pay — no charge. You'll never pay for a fix that didn't happen.
Do you work with Phaser, WebGL, or Three.js games?
Yes. I work with Phaser 3, WebGL game builds, Three.js, and vanilla javascript games. If it runs in a browser as an HTML5 or javascript game, I can debug it.
My game was built by someone else can you still fix it?
Yes. I regularly work with inherited code and third-party online game projects. As long as you have the source files, I can dig in and fix what's broken.
How do I share my game with you?
Send a live link or zip up your project files. No technical knowledge needed — just describe the problem in plain English and I'll handle everything from there.
