Time Layer — Playtest 03

First public source release of a small Codex-built Unreal Engine C++ puzzle game.

• Two connected rooms and two eras.
• A bridge/security/power-cell puzzle followed by a three-ring resonance puzzle.
• Native interaction, collision, pause menus and in-session checkpoints.
• 63 in-engine functional checks completed on the development Mac.
• Pure puzzle-rule CI passes, including all 64 phase combinations.
• Original project content is MIT; Unreal Engine is separately installed/licensed.

Important limitations

This is a source project, not a packaged executable. Tested with Unreal Engine
5.8.2, Xcode 26.4 and Apple Silicon. No persistent saves, networking, controller
support or cross-platform validation. An editor shutdown anomaly remains
unresolved; long-session stability is not established. See README for setup.
