About this service
Summary
FAQs
Do you also handle game design or just programming?
Both — I personally design and code every system, from player mechanics to AI and UI feedback. My focus is on ensuring the feel of gameplay matches the design intent — responsive, fluid, and satisfying. Full portfolio here https://on.contra.com/KGhGhm
Will the project include multiplayer?
Multiplayer support (via Photon, Mirror, or Unreal GAS/Replication) can be added as an optional feature in a separate milestone. For the base service, I focus on single-player systems with clean architecture ready for multiplayer extension.
What platforms can the game run on?
The prototype can target Windows, macOS, or WebGL. With small adjustments, it can also be prepared for console or VR deployment if required.
Can you deliver a playable demo for investors or Steam page?
Absolutely — I can prepare a vertical slice build optimized for presentation, trailers, or funding pitches, complete with UI polish and gameplay recording options.
Who owns the final project?
You retain full ownership of all code, assets, and documentation after final payment. The project will be delivered with clear folder structure and setup instructions.
What engine do you recommend — Unity or Unreal?
Unity: great for quick prototyping, mobile/web versions, and flexibility. Unreal: ideal for cinematic shooters, realistic visuals, and performance-heavy projects. We can decide together based on your goals and budget.
How do payments work?
Payments are managed securely through Contra escrow. Each milestone is funded upfront and released once the deliverables are approved by you.
Do you provide post-launch support or updates?
Yes — I offer optional post-delivery support for debugging, optimization, or feature extensions. Many clients choose to keep me on a monthly retainer to continue improving the prototype or build multiplayer modes later.
