hi! this is the version of the game that came out before the Kickstarter. It has two Incursions (the story of two of the Masks) and is incomplete.
I'm working on the final version (which will include an Incursion for each Mask), and Kickstarter backers will get it first. The Kickstarter is also the only way to get a physical copy of the game :) I hope that answers your question!
