I couldn't find an example anywhere on the forums that demonstrated how to save and load an entire Array to/from WebStorage without plugins, so figured I'd upload one.
It's fairly well commented so hopefully it's fairly easy to understand, let me know though!
This is probably pretty useful if you want to generate and then save a random map for example, or just saving level scores, times etc.

CAPX - Here
Hope somebody finds it helpful! =)
Also, this example is only for 2D Arrays, but you could easily add another loop in for 3D if you wanted =)
