Hi, I like the overall atmosphere and theme of the game in general. I think being stranded on a ship and your running out of oxygen is an interesting concept. I did, however, run into a good bit of bugs whilst playing this that kinda took me out of the experience and lowered the overall enjoyment level of the experience for me. The biggest one that I see other people have ran into is that the lights seem to have become attached to my player's back. That can make it rather difficult to navigate in darker spaces and to pinpoint what exactly one is looking at.
Another bug I came across that seemed to keep me from progress any further was when I picked the third tool, which I didn't really get to see what the name was as the text disappeared too fast on me after picking it up, but I was standing near the one green pillar and doing the data transfer thing and the green bar filled up completely and it said it was complete, but after that nothing happened...
I think another area that is a little lacking that would add a lot more depth is just music or ambiance in general, other than the heavy breathing of the character and the slight bit you have at the start. I feel this would add a lot more to the overall feel of dread for the player.
Overall, though, a decent job with what you got done, just a few bug fixes and maybe the implementation of some more SFX, and you'd have something really good in my own opinion.
