This app is really nice for what it offers, the storytelling and just general establishing your own story and it's paths with the AI is nice, my current gripe is the Deepseek AI they own is the most cost effective but they've been lowering the context limits from 128,000 to 110,000, which is really annoying as the other good AIs' cost too much or they're not good. I would love for more context and not less, aside from that I can't seem to stay signed in for some reason and have to sign in.

It's kinda nice. Especially considering the fact that you can create your own storyline. The downside is that it's really hard to get the mana (I mean really hard, considering that the ads only give 0.2-0.8ish for every ad), the slow loading (but that's because of the AI) although I do have problems with ads being slow to load as well. My hope is that maybe one day they'll make it so that mana could be recharged by itself slowly.

i love these create your destiny story. but the problem is once you used up mana and arcane and you use the free version, all those stories and relationships you built up will goes to nothing, as the free version doesn't save memories and the relationships you built up will eventually lost and the ai will make another branchline. at least make the free version continue the memories of the story you painstakingly made for hours and days, just to reset for nothing.
