Well. That ate an entire day trying to figure out but you want to use JSON.parse();
But if you're indexing, you need to first insert ANY value into the index, then you can overwrite that data with your parsed string.
The end result is I have a complex game in C3 with my own load/save function using ONLY json. A bit clunky but the freedom to create is now before me -- I'm super frustrated with a few features in C3 man... Object selection and data manipulation aren't great. 4/10.
Anyway here's the solution..
