Thanks! I started working on the implementation.
Also while at it, I think I'll probably also be able to support columns and statues if you'll add them.
Hey! I've added information about round rooms, columns and flooded tiles to exported JSON.
Looks great! And I like the addition of a version number :P
I'll start implementing these right away, and I'll also look into importing the text - or at least, the room numbers.
Done! Thanks for your help.
