FAQ
What kind of games do you support?
I work with HTML5 and JavaScript-based games — especially canvas-driven or DOM-based browser games. No Unity/Unreal projects (yet!).
What does “prototype” include?
A single game mechanic or system (i.e. movement logic, a functional inventory, or enemy patrol AI). Think of it as a modular building block, not a full game.
Can you diagnose unknown bugs?
Absolutely! I’m happy to take a look and help identify the issue. If it goes beyond this gig’s scope, I’ll quote a custom offer.
