Cool game! It's nice to see a non-pixel-art game for a change! The visuals are really good and the music complements it.
I struggled a bit with the controls in the beginning and understand what it is I have to do. I suggest placing an easy fuel container very close to the mothership to show the player quickly what they have to do.
The game progresses really nicely and keeps looking better and better.
Congrats on submitting!
