Ratings and reviews

The game is fun though admittedly I only use it to create "worlds" I have almost 100 so far. the only issue I have is that you can only create 2 landmarks inside one World and one of my worlds is literally defined by endless landmarks but other than that the game is pretty fun. I have not used the AI or multiplayer yet but plan too once I have enough props made to actually DM and walk people through it. please add an option to add more landmarks in one world.

This app is pretty cool, daily mana, interesting stories, I only have two things I wish it had and that's a longer word limit (at least 500 characters if possible) and some details are forgotten by the bot during creation. I am also rather displeased that the unpaid daily reward is a singular mana, really puts a damper on the free creativity. Other than that, it's a great app and I plan to enjoy playing it a bunch.

Fun idea. Hit or miss with the prompts (but hey, that's A.I. for you). Don't know how to get multiple pictures for a summon. Some features are locked behind a paywall, which is a real shame. I would rather be subjected to a few ads than have a paywall that isn't really worth paying for, or use a donation system. If you think your app is that great, then people would donate to use it. Just saying. Still worth downloading and playing around with.
