I will develop your game idea into a polished playable prototype


Level 1
About this gig
Have a game idea but need something real you can play, test, or pitch? I turn your concept into a focused playable prototype or vertical slice. Instead of forcing every project into the same engine, I select Unreal Engine, Unity, or Godot based on your gameplay, visual goals, target platform, production scope, and future roadmap. You receive a playable build for the agreed platform, a clean structured source project, custom gameplay mechanics and a clear core loop, a greybox level or scene and basic UI, integration of supplied or properly licensed assets, testing and refinement, clear progress updates, and concise handover notes. This gig is ideal for validating an idea, demonstrating a mechanic, preparing a pitch, or creating the technical foundation for further production. The packages cover focused prototype scopes, not an undefined complete game. Multiplayer, backend services, custom art, large worlds, store publishing, and console certification require a custom offer. Please message me before ordering. I will review your brief, define the smallest useful scope, and confirm the right engine, package, milestones, and deliverables.

FAQ
Which engine will you use?
I select Unreal Engine, Unity, or Godot based on the gameplay, visual target, platform, delivery scope, and future roadmap. I confirm the recommendation before development starts.
Can I request a specific engine?
Yes. Tell me which engine and version you prefer. I will confirm whether it is the right fit for the agreed prototype and target platform before you order.
Is this a complete commercial game?
The packages focus on a defined prototype or vertical slice. A complete game may be possible through a custom offer and milestone plan after the scope has been reviewed.
Will I receive the complete source project?
Yes. Every package includes the organized source project, relevant code or visual scripts, and the agreed playable build.
Are custom artwork and audio included?
I integrate your supplied or properly licensed assets. Creating original art, animation, music, or sound is not included unless it is explicitly added to a custom offer.
What counts as a revision?
A revision is an adjustment to the agreed implementation or presentation. New systems, features, areas, or changes to the approved scope require a separate quote.
Can the prototype include multiplayer, VR, mobile, or Web?
These targets may be possible through a custom offer. The standard packages assume a focused single-player prototype for one agreed platform unless stated otherwise.
