Polish TPS Game for Portals

My third-person shooter is feature-complete, but it still feels rough around the edges. Before I submit it to CrazyGames and Poki I need a final production pass that makes every moment feel smooth, juicy, and professionally finished.

Here is what I expect you to tackle:
• Graphics – tighten shaders, lighting, VFX and optimise textures so the WebGL build loads fast but still pops on screen.
• Audio – remaster the soundtrack, rebalance SFX and hook in responsive layers (e.g. pitch, filters) that react to gameplay.
• Gameplay mechanics – fine-tune movement, shooting feedback, hit-stop, camera shake and difficulty curves so the core loop feels crisp and addictive.
• UI/UX – polish menus, HUD, buttons and transitions for keyboard, mouse and touch; add subtle motion and sound cues.
• Misc polish – bug fixes, performance profiling, code cleanliness, compression and any last-mile touches a portal reviewer would flag.

Deliverables
1. Web build (and project files) that passes the quality tests of CrazyGames and Poki.
2. A change-log explaining every improvement.
3. Submission-ready screenshots, icons and short trailer clips if needed.

I will release the agreed payment immediately once at least one of the two portals approves the game, and I am happy to negotiate a bonus when both green-light it. Let me know the tools you prefer—Unity, Godot, Unreal Web export, etc.—and a realistic timeframe so we can lock this in quickly.
