I've finally finished the new example project. It uses new art and shows the full power of the built-in UI editor. Everything is made inside StoryFlow Editor - no extra game engines.
You can play it here: https://storyflow-editor.com/play/the-beast-of-millhaven/new/
Some features shown in the project:
Animated UI elements
Character creator
Shop UI
Drag and drop player inventory
Movable windows
Combat with damage numbers
It's coming in the next update. The update is mostly done, I just need a bit more time to fix some remaining issues and make some improvements.
