Hey. Thanks for you question.
The game will end with chapter 20 latest - the game's complexity is to hight to continue after that. I think and hope that will be at the end of 2025.
I'm not sure what to do after that. Either I'll develop a follow-up game for the family or a completely new game or I take a break from game development.
Either way, I've several ideas for a follow - up game, but I'm also open for new ideas.
Regards MCK
