The verdict
A surprisingly strategic space-mining idle where the real game is selling galaxies, not building them. Deep upgrade scaling, live tournaments, and a mothership economy that rewards genuine optimization — as long as you can look past the ads.
Hot take
Underneath the free-to-play wrapping is a legitimately math-heavy prestige game. The $9.99 ad-removal is basically the real price of admission, and honestly it's worth it — the loop underneath is that good.
