Can someone give me a guide/walkthrough?my pc kind of potato and my heart can't take lissa shit anymore
It's not worth it, man. I haven't played through all the endings but from what I understand even the "good" ones are unsatisfying. It's not a feel-good VN, it's trying to "make you think" about the conventions of the medium... or something. From what I've seen of it, in my opinion it's not even doing a particularly good job of that. At least I sincerely hope it was intended to be subversive, because if the characters in this were written to be genuinely interesting or sympathetic in and of themselves, then the author must be absolutely delusional.
At first I thought it was trying to put characters with more realistic traits and their own significant baggage to deal with into a stereotypical H-game setting. That seemed interesting, but then all the characters just turn out to be unbelievable psycho monsters in like 80% of the endings. It's not even given much justification, in most cases it just comes out of nowhere and then the game is abruptly over. IDK if the game was rushed for some reason or if that's how it's supposed to be, but in any case any message this game is trying to get across isn't nearly interesting enough to justify playing through 15 endings, and the "good" endings aren't worth the trouble.
