Great concept! I liked the exploration aspect to this game. The management of health and oxygen also added a nice element to the gameplay. Awesome job!

Really awesome level design! I stupidly had my headset turned down initially and thought you didn't include audio because you were in the vacuum of space :p But my stupidity gave me the idea that perhaps you could remove all the audio and just have the sound of breathing inside your helmet, which would then become more struggled when you started running low on oxygen? Could make for a very atmospheric and intense experience :)

Other than that I really loved the game, I personally would have preferred simple WASD controls but maybe that's just a preference. Also wasn't sure how the jump mechanic worked initially and I yeeted myself into space lol.

you can tell that a lot of effort went into the game. 
it has its own vibe and concept. there is a fair amount of variety,
jumping outside, walking on metal outside the spaceship, oxygen management,
putting out the fire, repairing the ship,  
i just think it would be very nice if there was a save system as the oxygen i think a bit is tight.
and it takes a moment until you have played your way to the point of death again.
 otherways nice game

I love how this plays, really impressive especially considering the 3-day time limit!
