Thanks for playing and for the detailed feedback! 🏰
You're absolutely right—currently, the game doesn't have a formal "end screen" or final notification after conquering the entire map. Once you've turned the whole island black and maxed out your castle upgrades, you've essentially reached the current end of available content.
Spoiler :max castle level is 10
That said, I'm actively working on bug fixes and improvements based on your feedback. Your progress and dedication truly help shape what comes next. Stay tuned for updates—and feel free to share any ideas or features you'd love to see!
