Excellent presentation.  There were so many nice little bits of polish you put in there like the tutorial voice overs.  The audio design was fantastic and created a really eerie atmosphere.  I got stuck though after I used a battery to open a crawl space but then I reached a ledge in the crawl space I couldn't jump over.  Overall this was really impressive!

• This retro effect could be more mild. My eyes got tired fast :( I would compare it with blur effect. Some people just turn it off first they start playing new games.
• Controls description is badly positioned because you have to figure out how to get to this description :)
• Flashlight could be more bright.

Otherwise, I liked playing your game. It's being 3D is already deserves some praise. The environment, animation and the implementation of the virtual voice is fantastic. Have you made all the props by yourself?

• Nice art style and vibes with the glowing lights, background ambience 
• I like how you activate low gravity and backtrack through the same earlier parts which are now different.
• I didn’t expect to crouch on C (ctrl is commonly used)
• I didn’t progress past the vent in the second level, it looked like a doorstep I couldn’t jump over. The game was interesting and I would have played further if I knew how to.

Really dark, really hard to look. The details in this game is moderately good and the retro filter make the game looks nicer but also make it harder to look :P. I sometimes doesn't know the purpose of the keys and items picked up during the gameplay.

I wish I could find more good thing to say about this game, but I would say the game looks nice. Good job.

Love the environment that was built and the music fits it so well.  Also the arm animation for viewing the oxygen level is so badass lol
