[How to Launch]

Double-click Yukemuri-Seethrough.exe to launch.
* The title screen starts in desktop mode. Switch to VR mode after entering the game proper.

To play in VR
0. Install SteamVR beforehand and complete its setup.
1. Launch SteamVR and connect your VR headset.
* For Quest / Pico PCVR environments, streaming via Virtual Desktop is recommended.
2. Launch the game, advance past the title to the game proper, then press 3 to switch to VR mode.
(Press 1 or 2 to switch back to first / third-person desktop.)

* Stopping SteamVR while it is running may cause the game to error out. Please be aware.
* Desktop mode disables VR rendering automatically — you do NOT need to turn SteamVR off for performance.

[Notes]
- If the install path contains full-width characters (Japanese, etc.) or spaces, SteamVR may fail to
register controller input due to its own limitations. Please choose a path carefully.
- In-game keys: 1 = first-person desktop, 2 = third-person desktop, 3 = VR.
- VR and 1st-person modes can induce motion sickness at low frame rates. We recommend playing in
an environment where a comfortable frame rate can be maintained.
- In VR mode, real-time mirror reflections are disabled. This is intentional, as the rendering
cost would be too high in VR. Thank you for your understanding.

[Prohibited]
- Analysis, modification, and reverse engineering are prohibited.
- Redistribution, piracy, and resale are prohibited.
