Is there anyway to load your own art into this and generate your own dungeons?

You'd have to download the app with the dev tools or wget, run locally and provide own replacements for each image (or change the code - it's rather simple, maybe even primitive - a bit if you have more/less assets)
If it's like "let's make it a feature" - very unlikely I'll find time for such a thing.
