This is great! I love the classic elements combined with modern features like the search in the menu. Firefox looks surprisingly good with the theme too :)
This is the setup I have on GeckoLinux, a distro based on OpenSuse Tumbleweed. I am using this on my main laptop as my main Distribution right now. I primarily use it for communication, work, and web-browsing, with gaming over steam and lutris being a side activity.
I am running XFCE with the Chicago 95 theme using a horizontal deskbar. I have a lot of minor changes to some settings that I used to make things look how I like them. For the menu icon and wallpaper, I have the character Xenia, an almost mascot for Linux.
It might be because if it's anything like spiral linux by the same creator, it's likely (more-or-less) just a pre-customized install rather than its own distro with its own repos and whatnot. Meaning that an old image would just update to a new version of opensuse with all changes and tweaks intact
