Apex — if this first movement milestone is still open, I made a small runnable Godot 4.5 fixture for the controls you described: walking, grounded sprint/stamina, mouse look, wall collision, camera pitch limits and pause/cursor release.
Free source: https://nebulakit.itch.io/nebula-backdrop-godot — scroll to Download demo and choose NebulaKit-First-Person-Movement-Proof-20261012.zip. No purchase needed; the backdrop browser demo and paid kit are separate. Import project.godot in Godot 4.5 and press F5.
This is newly made AI-assisted example code, not a previously shipped first-person game. Windows/Compatibility native checks are technical QA, not human horror-feel testing or proof in your project.
If AI-assisted development is acceptable, I can assess a movement-only pilot at an indicative US$100, subject to project review and written confirmation. The scope would be integration into one existing desktop scene, source changes, verification steps, rollback notes and one correction pass against the agreed acceptance. Crouch, footsteps, interactions/items, enemy AI and saving would be separate. Exact scope, price, delivery date and payment arrangements need confirmation after project review; this message does not accept a job.
Which exact Godot version, renderer and target desktop platform are you using? A public demo is useful if available; we can arrange private sharing of an authorized stripped project after the initial fit check. Please keep private assets and credentials out of the public thread. You can reply here or email omribe@gmail.com with “Small software fix - fit check”.
