Same issue. That means you either have to put the master volume very low or to record your voice seperatly.

Did not reoccur (only occurred twice). Hence, not a bug.

I agree that the oxygen and battery consumption limits the time spent in exploration. However, it makes you plan your trips/journeys before leaving the habitat and makes the game more realistic.

I'll do so if it reoccurs and post the link below.

Yeah, to be honest, I was surprisingly happy when I found the second habitat in the middle of nowhere.

Controllers would solve that problem.

Will Xbox One controllers be fully supported / compatible ?  I think it would make the gameplay more fluid (even though it is already quite fluid).  

It does say on the pad that they are indicated on the scanner (purple circle). However, I only see one of the habitat (Alpha) and stuggle to find the others as well.

I think there should be a note somewhere in the habitat telling the player that sleep is important as it helps to recover stamina (even though it seems logic).

However, I wouldn't tell the player that he is running low on stamina as I assume they should figure it out for themselves. It makes the game more realistic and forces the players to think before they do something.

All you could do is add an effect to make the player's vision slightly blurry when exhausted, which would be a good indicator of the player's current stamina level.
