Your reaction was almost exactly the same as mine. The very first thing that made me realize that Rosebud was a big deal was how consistently accurate the AI was when it came to figuring out what was wrong with a project.

Having a debugging assistant that is that good, in my opinion, alone makes Rosebud a better option than most 2D game development environments for most people.

The issues with the incomplete code get in the way, but the team has already identified them, so they shouldn't be a problem for too much longer.
