That was quite a chilling game! A welcome change from the dime-a-dozen jump scare games.
Firstly, the sounds were used very well and were responsible for most of the atmosphere.
The music was also good, especially at the beginning.
This style reminded me awfully of Gyossait and the story reminded me of the movie Sunshine.
You executed the sense of being all alone and helpless really well.
Also, I felt the walking animation could have been better, the speed is fine for this kind of a game.
17 MB is a lot for a game so simple. I've seen games with better graphics taking up half this size. It may seem very silly for most people but it's a great problem for others with slow internet. It took me 20 minutes to get this game to load fully. :-(
Medals always make a game more enjoyable, you didn't disappoint there.
All in all, a great piece of work. Expecting more bone chilling games soon.
Cheers !
