/jp/ - Otaku Culture

So I just started playing this, the wiki and guides have been super helpful thus far. The only thing that has been killing me lately is managing fuel, after looking I guess I have to make it out of the first area in order to actually start gaining resources from sorties, I almost had a heart attack when I was down to nothing until I realized they give you resources over time. Should I grind a bit more before trying to challenge the 1-4 boss? I keep trying to challenge the 1-3 boss but I keep having shit luck steering me away from it. I have to say though so far this game is super fun and super addicting.
