I really liked the concept and story for the game, though the game itself felt less fun than I expected. The tradeoff between delivering fuel to the core and using fuel to find more fuel was a really great idea, and I enjoyed exploring the universe and finding planets.
The fuel consumption and scarcity felt unbalanced to me; I was always running out of fuel even if only had to do small course corrections. I didn't really hit a situation where spending the time to drop crew members on a planet helped me in the long run - it would take too long even if I had a decent number of crew members there. I also never had the opportunity to worry about the space in my ship. If the fuel was balanced better (perhaps if turning cost less fuel, to make discovery more fun and less frustrating) this could be a really great game.
It would be neat if the HUD could distinguish planets with lifeforms and oil from those without - I sometimes felt like I would waste time investigating a planet which turned out to be unhelpful. Also, once I saw a planet on the HUD that was outside of the crunch; that was a surprise!
Great work on this! Despite being unbalanced I still enjoyed it. I often felt like I was rescuing people from annihilation as I took them off planets just about to be crunched, which was neat. With some more balancing it could be spectacular!
