I enjoyed this a lot, I found holding space to connect a bit unintuitive, I think left/right mouse would be better, or space once to connect and space again to disconnect I enjoyed flinging myself around from the fuel tanks. Needs some polish and some work to be more readable to players but a fun game that I enjoyed. 

Absolutely loved it!

Please let me know if there's anything after the player gets told they're dead, it seems like a sad end to a fun little game.

I had some issues understanding that you have to hold space to tether, got me killed 3 times, might be something to think about.

Fuel isn't really well explained, I finally understood that I get fuel only for that one push and then I'm out (which doesn't read well, since it works exactly like the oxygen otherwise, so I expected to "fuel up" - and I didn't).

Other than that, it's agreat idea, very well made, has character, the writing is good (I was like south-west? in space? and then the character asked the same thing - brilliant), I strongly suggest everyone to play this one ^^

The art is very, very good. I also like your choice of font.

One little thing I feel I must mention. When the submission form asks "How does your game fit the theme?", it's asking for you to explain how your game fits the theme. Saying it fits well doesn't explain your reasoning or provide for further dialogue or even understanding. And a proper answer to that question is a criterion for judging the game.
