thanks for your lovely comment, it made the entire team giggle with glee when we read it today. We're happy to hear you are still having an amazing time playing Passing By, especially after such a long time.
The theme of finding a home and settling down are indeed ones that work perfectly with the narrative of the game, but as you said, there is also the existing code base, and making games is always about finding a middle ground between many elements such as art, story, and programming. However, the current ending of the game is not so different from what you describe - maybe you just haven't found it yet?
Let us know, because our credits definitely DO roll, even though the letter remains a mystery. ;)
Thank you for playing and constantly leaving feedback, it means a lot to the team! Happy ballooning, fellow traveller!
