There will be only one ending (1.40) and some free-play variation. Afterwards if there is interest I plan to do a few "episodes" covering stuff I didn't want in the main story.I'm all for pre-determining an end point for a story and working towards it instead of leaving it open ended, ("Lost In Space").
With all that you've learned making this game and all of the work in evolving the characters, will there be a Space Journey X - Part 2 in the future?
(I'm still hoping for the oversexed lizard ladies of Zebulon or maybe even the Wild Women of Wongo, . . . . )
Once those are done by the end of the year I am probably moving to the next project (Some Hermione / Little Witch Academia / Wizarding Story / Working Title: "The College of Magical Things")
