As for the changes to the VR mode, they were bigger.
The mode of operation didn't matter. It was controlled by consciousness anyway. The key was the visual performance.
One of the highlights of the original "escape from death" was the movie-level storyboard and two-person split-screen operation. If they wanted to make it into VR mode, the storyboard was easy, but the split-screen was difficult.
If the screen was split in VR, the player would probably have a mental breakdown, and it would be terrible to stare at the left or right side for a long time. After all, PC and Switch's display was flat, while VR had a full view. It was impossible to copy it.
However, VR mode was still necessary. High-precision art resources supported VR, and story mode was also very suitable, so VR mode would adopt a different image presentation method from Switch.
