There's a walkthrough on Underbliss's Tumblr that goes up through the CasCas (no farther, unfortunately, but it should get you through)
It helped me through my second playthrough. My first one I managed to beat it with out understanding what madness points are. Now I can't even unlock the first option with the Cas-Cas during any other play through. I'm thinking im either too high of madness or too low of madness. Can anyone tell me what or how to get the madness points are?
Hi! I'm sorry I don't have anything more 'official' to offer, but regarding madness (which is, essentially, a measure of how far you've let the Cuthintal... in/take control/take over), I wrote up a list of ways to gain madness before on Discord. I found it, posted it, I hope that helps you guys in some way!
