Hi! Thanks for trying it! Sometimes the agent can get tripped up if it doesn't have a component that matches the theme. For example, I can tell you I don't have a rocketship asset or alien asset, so it might default to something to generic in replacement. And also we have lots of pirate assets, so then it might lean toward a pirate-theme if it sees the word "island."
That said - I just noticed a bug making them overly generic. Fixing right now!
not a lot of horror assets either unfortunately. i wanted ghosts and ghouls and zombie tiki with my pirates but got industrial wasteland and candyland.
You should be able to prompt to create your own horror assets, but it might take some time for them to build though!
