It was a bit hard to understand what to do, both in VR and as the pc player. My pc friend liked to highlight but I don’t think it should be highlighted in VR as well. When I held an object and it was highlighted it obstructed my view. When he stopped highlighting it was still highlighted for me until he switched it off again.
After some time we figured out how the battery and oxygen worked but then once my friend got the mission to be evil. I did not understand why he did not want to open doors for me all suddenly. The game was hard enough when we played together and I cannot see how it would be possible without my AI friend.
We decided to play together even though he was the evil AI. The problem with this was that I lost when I got to the ship. This made us think, the AI should always play as friendly as possible? If the player manages to get to the ship he will want to bring the AI because he will think of it is as friendly and then the evil AI win? And if the AI was friendly he also win. Did it matter if the doors were open or not for the oxygen? Otherwise the AI should always open as many doors as possible?
The game really needed some audio and music but I see that you wrote that you were thinking about that but ran out of time.
