Oh, that second key was just left over from earlier tinkering with the level. I probably should have deleted it.
One thing I'd suggest in the component editor would be that when you click the revealer it doesn't only show the fields you can edit but it also starts with a line or two of text about what the component does and what you're adjusting in the fields. That would go a long way to helping level authors help themselves, and I suspect it would be pretty easy to implement.
Anyway, I hope you keep developing this. I love games that have a creative component to them.
