Hey Yumi! I thought your game was so cool and unique that I put an easter egg of it in my game Red Pines :) well done!
You have a keen eye! If you want I can send you that asset to keep for yourself, just let me know where to send it to. Also I won't make you get the full completion to unlock it so type "day" in the main menu or extras menu, try the GB Bonus Scene ;)
Edit: Download the latest version! I can't believe I didn't find some bugs that were there.
