Game Development

Try your game idea through a small 2D single-player build. Game Prototype focuses on one core mechanic and one small test level. Playable Demo develops one core loop across up to three small levels, with basic menus and a local progress save. Both suit businesses and individuals worldwide, with one platform, input scheme and language, using supplied or agreed licensed assets. 3D, multiplayer and wider release plans need a separate quote.

Package scope and handover

Small enough to test and play.

One platform and input scheme
We agree a browser target or one desktop operating system, supported devices, and one input scheme before kickoff. Extra platforms, control schemes, and larger levels sit outside the package.
Assets and playability
You supply assets or approve suitable licensed assets. We agree gameplay, level size, and acceptance checks together before building the prototype or demo. A full commercial release needs its own scope.
Your inputs and accounts
We confirm fit, scope, one language, and required access before work. You supply final content, branding, approved policies, and suitable provider accounts. Accounts and licenses stay in your name.
Two payment milestones
50% at kickoff. The remaining 50% is due after you approve the preview, before any agreed activation and handover.
A schedule we agree together
Estimates begin after we receive the deposit, complete inputs, and access. Timing depends on compatibility, provider approvals where needed, and timely, consolidated feedback.
Handover and agreed-scope fixes
The agreed deliverables and any included walkthrough follow final payment. For 14 days after handover, corrections for failures against the agreed scope are included. New requirements and ongoing maintenance are quoted separately.
Agreed acceptance checks
We agree acceptance checks before work and review the deliverables against them before handover. Prototypes and review reports are checked against their agreed questions and scope.
