- Happy New Year - 31 December 2025
It's hard to believe how fast time flies. The year "2025" still sounds incredibly futuristic and sci-fi to me, but in just one more day, it will be history. Maybe in the blink of an eye, we'll be welcoming 2033 😁. I wonder... Jodi should be in high school around now, right? 😊 This week, we continued our work from last week, and we'll be taking a few days off for the holiday. The DLC is still in development with nothing major to share yet, so yesterday we took some time to create three "Happy New Year" 4K wallpapers. We hope you like them! Wishing everyone a wonderful New Year. May all your beautiful wishes come true! (Image assets used in the wallpapers are from https://pixabay.com/.)
