It's refreshing to see some cosmic waifu representation! The gameplay is interesting. You fly around and recapture planets from enemy forces, then assign your girls to them and construct buildings on them in order to gain more resources to summon more girls. Summoning works similarly to Girls Frontline, if you've ever played it. Using different amounts of resources yields different results, so it's pretty F2P friendly on that front. However, other things, like increasing your team size and the amount of girls you can assign to a planet/asteroid cost cubes, which are the premium currency. Thankfully there are affordable options, but it would be nice if the costs for the upgrades were decreased a bit. I want to support this game, though, and I hope it gains more traction. I'm super thankful it has an English option, though all of the announcements seem to be in Korean.
