I've used Kit several times now and it performs flawlessly. It has potential to make Wherigo mainstream.
If I want to expand a little, for the audience to interact with characters and items, or perhaps have a choice in Wherigo paths they choose, am I best off laying down the groundwork in kit and then exporting to another builder? Or should I be doing everything in another builder? Will the kit ever add characters/items/item dependent zones (if yes then I will wait!)
