Thanks for all the kind words!
Yes, we had to change our story controller, and this unfortunately broke older saves. Much like the change in art direction, I know losing saves sucks, and it wasn't an easy decision.
Changes like these will however allow us to continue working on and expanding Infinite Stars in new directions for years to come! <3
