My oxygen depleted exactly as I reached the spider the first time so I thought it killed me! Then I noticed bottles to refill the oxygen so I understood that was the limiting resource. I know that the idea of the game is to play someone with a lack of memory but it really feels like we don't have enough clear objectives. Once I understood the spider was friendly and I followed it, it just entered the teleporter without giving me any idea of what I needed to do. So I kept dying again and again the lack of oxygen and getting lost in the spacecraft's labyrinth.
But the environment and visuals and very nice and polished and I like the little cinematic at the beginning, so well done ;)
