The GOG write-up says this:
Q: Do I need a VR headset to play Myst?
A: You do not need a VR headset to play Myst. Myst is playable with or without a VR headset.
BUILT FOR BOTH VR AND 2D DISPLAYS
Designed and built from the ground up in Unreal Engine, this newly-reimagined version of Myst includes fresh takes on the visuals in every area in the game. With both VR and 2D play experiences in mind, this definitive, modern edition of Myst will immerse you in the world in a way that has never been possible before.
The VR experience includes both Free Roam and Teleport modes, and supports Valve Index, HTC Vive, Oculus Rift, Rift S, and Quest via Oculus Link.
Additionally, Myst includes many “comfort level” features for both new and experienced VR users, including the option to enable smooth or snap turning, quick travel up stairs and ladders, vertical height quantization, and more!
