Hi Kevin,
are there any plans for an alternative usage of catalysts and rubies? For challenge tokens there are plenty of options you can buy with them, but catalysts and rubies are getting quite worthless at a certain point of the game...
Thank you for the code!
Catalysts might be a ways off, but Rubies I can see happening pretty soon. I mentioned elsewhere that they might be used for missions, or as u/egrutz2 suggested, something to help speed up your runs.
