I’m building a tightly scoped, fast-paced action game for PC and need a complete playable version delivered within a month. The core idea is an arena-style experience with responsive controls, fluid character movement, and impactful combat. I already have a high-level game design document covering mechanics, enemy behaviors, level flow, and art direction. What’s missing is the full implementation: coding the gameplay loop, integrating placeholder or readily available art/audio, and packaging the build so it runs flawlessly on Windows. Unity or Unreal Engine are both acceptable; pick whichever lets you hit 60 fps on mid-range hardware with minimal load times. Deliverables: • Compiled PC build ready to install and play • Well-commented source project and scripts • Brief setup document explaining how to open, build, and extend the project Acceptance criteria: • All listed mechanics function as described in the GDD • No critical crashes or soft-locks across a 20-minute continuous session • Average frame rate ≥60 fps on a GTX 1060 / Ryzen 5 system Once I receive the first playable, we’ll iterate twice on polish and minor tweaks before final hand-off.
