GreenHealthScholarship/Virtual-Metro-Scenario-for-Mental-Health-Rehabilitation ? reverse-engineered prompt

Build me a Unity VR serious game prototype set in a metro station and train, meant to support rehabilitation research for schizophrenia. I want the player to move through a realistic virtual metro scenario, interact with the environment and a few NPCs, and experience a calm but immersive test space that could later be expanded with therapeutic features.

Please make it work for Meta Quest 2, and leave room for bHaptics vest support so touch feedback can be added for objects and NPC interactions. Also set it up so heart rate data from an Apple Watch can be read in and shown or stored for later analysis, since that matters for the research side.

Keep the project clean and easy to extend, with the main gameplay loop focused on exploring the metro scenario and collecting user data for adaptation testing. If you need to look up current Unity or device integration docs online, go ahead.
