Ok, so a "Sacrifice" button showed up. No explanation.
I clicked it and everything seemed to reset without any noticable gain or explanation.
I started a new round and everything is black now
:(
EDIT: Reloaded the page, now theres a "Prestige"button. Clicking it just starts a new round? And theres sometimes (?) a prestige menu but I cannot purchase anything since I seem to not have prestige points?
