Thank you for your response. We've completed some simple updates, including castle upgrades and addressing the issue with auto-aiming locking onto the Boss in the final level.
However, improving the problem with manual aiming requires more time, and we've tried some adjustments that don't feel perfect. :( We are considering exploring other types of games. After completing the next project, it might allow us more time to think about better solutions.
It's our honor to bring joy to you :)
