good question! I'd say similar in web where ideally the agent doesn't stray too far from creating new components. I noticed that happening here as well unless you directly prompt for it.

But the design system follows a set of rules and skill files and applies them when needed!

Hey, thanks so much for the feedback although obviously hurts a bit for wanting something I just created for fun to go into oblivion.

I totally understand your feedback though. The issue is that AI costs a lot of money under the hood, and so we needed some way to know if a user was hitting a limit. Will think about how to make that more clear upfront.

Thanks again for your feedback.

Originally we actually started messing around with 3D assets, which turned into RCT, then we learned about Ramp Labs! Very cool project as well. There's is more "how can AI play RCT" whereas this is "how can we construct theme parks using components"

oh wow, I'm surprised it edited the assets to look like that!

You should be able to prompt to create your own horror assets, but it might take some time for them to build though!

that's fair. Thanks for your feedback!

Perhaps more exciting: build a chocolate factory slide and river with a hot fudge river... haha

oooh! Fun idea. I think this might actually work... if you upload an image + prompt it to make a theme park referencing the map.

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!

that's kind of you to write, thanks for reading. Do you like RollerCoaster Tycoon too?! Anything we can make better?

I built an agent that helps you build Rollercoaster Tycoon-influenced theme parks. You can prompt something like “Build me a cool theme park” and it’ll build a cohesive theme park with multiple worlds and connected with paths and rides.The weird part is that I built it using the same ideas we use to make AI-generated websites follow a company’s design system.I work as an engineer at Magic...
