I haven’t bought the game yet, so I can’t say anything regarding the specific gameplay.
I have, however, played games that have similar mechanics. Pressing a button to open a door is just lazy VR design. Having hands that move when your actual hands are not moving is really off putting and no game should do that. If you want to have a simplified reload, go for it. Maybe even with a button press, but don’t wave my hands around while doing so. As I understand it, however, there’s supposed to be an ultra game mode where you can reload manually.
