Are you designing a game narrative or want to make some sort of text adventure? Even if it's just prototyping or storyboarding the free and open source app Arrow can help. Under the MIT license, Arrow has no barrier to entry and it's quite fully featured. It's also built with Godot Engine, so extending it should be easy enough too.
Some of the features include:
- 100% Visual Development
- Free as in Freedom: No royalty, no strings attached
- Customizable Node System
- Adequate number of Built-in Node-types including:
- Variable Modifier,
- User Input,
- Macro (reusables,)
- and more.
- One-Click Playable Export
- JSON Export and Import
- VCS Friendly
Being able to easily export the entire project into a HTML file to play in a browser is great, makes it easy to share with others and gather feedback. I can see this being incredibly useful to all sorts of different people and it appears to work perfectly for that in my own testing with it.
Check it out free on GitHub. It comes pre-built and ready to go for Linux and Windows.
