I've been playing for about a month and a half. For a while I was more focused on getting currants, but now I have more than I know what to do with. I've decided to set my goals on learning more skills, but with brain space upgrade cards being about 100k of i points, it's not as easy as it is to get currants. What are your suggestions? So far I've been donating a lot to shrines (using hallowed powder) in order to get lots of imagination at once. Is there something really vital I'm missing?
