Journey Maker 1.52
Interactive story, comics and game creator.
Journey Maker allows you to create interactive stories, comics, cards, choose-your-own-adventure type games and more with zero programming. The Journey Maker projects can include MP3 sounds and can be deployed as either "Web Folders" or Mac Applications that can be served over the internet (if you have a web host provider).

What's New in Version 1.5.2:
Updated JM and IAVM to support increment/decrement for Registers (to be used with future functionality)
Background project diagnostics now take considerably less CPU overhead
The “Reload the current scene” event directive no longer requires the browser to physically reload the page
Created additional checks to prevent sporadic “Needs Compiling” messages
Fixed display bugs related to the “Set Register” and “Play Sound” Event rules
