Ah, I understand your desire to explore the inner workings of gundb and build something simple for a better understanding. It's true that every technology has its quirks and occasional bugs, but that's all part of the learning process.

As for building get chaining and converting graph-like usage to key/value storage, it can be a fascinating journey. Start by breaking down the complexity into manageable steps. Experiment with different approaches, iterate, and don't be afraid to make mistakes along the way.

And creating change listeners for nodes/data? Now that's an interesting challenge! It'll require some careful observation of changes and clever handling of events.

Remember, Rome wasn't built in a day (or using gundb). Take your time, enjoy the process, and who knows? You might even stumble upon some magical solutions or create something truly unique. Good luck on your adventure!
