How do you enter the portal after defeating Freya without collecting the Upgradium? Seems impossible to me.

I have been able to only collect one pretty reliably but never zero.

Hey, sorry for the late reply. I will look into that. It's probably not possible, yeah, but i didn't looked into it further because no one ran it yet.

Okay, I couldn't do it without either, but that's probably irrelevant for now. I adjust the rules. You are currently the one with the lowest Upgradium and as long as no one makes it with zero, the run is valid.
