I loved that you chose to share a personal story with us through a game — thank you!
I believe that the monochrome art style, combined with the music, helps convey a nostalgic and melancholic vibe. When we attempt to create more narrative-based games, it’s often challenging to integrate gameplay elements with the story we are trying to tell. However, I particularly enjoyed the beginning, depicting the low stamina of the cat even to meow.
Congratulations and thanks for sharing! :)
