I’m going to guess the ending you got was the ending where Jessie gets on a train. This is an actual end - one of her abrupt endings. If that is the ending you got, there’s another ending that explores further into her werewolf form, and that one would have the “to be continued” at the end of it! If it doesn’t then that’s probably a bug.
That said, the game is currently in development and this is the demo. The demo only goes up to chapter 2 for each romance, and we plan to release the full game on the 27th of December.
If you can’t wait that long, there is an early access build of the game that goes to the ending of Jessie, Marion, and 4 chapters of Grace that is available now on Patreon for a $3 pledge. Hope that helps! :B
