Ok, you might be asking yourself "39:18?, what is that?"
Well, that's one of this skin's supported aspect ratios.
Originally commissioned by Caredu in this very specific resolution, which was 1300x600, or, when converted to an aspect ratio, 39:18.
After the commission was finished it was later released in the more conventional 16:9 and 21:9 aspect ratios for everyone to enjoy, however, the 39:18 version can also be downloaded, if you happen to be playing in this specific window size, it might be of use to you.
Alice Zuberg is available in the previously mentioned aspect ratios, if you're unsure which version is best for you, take a look at the screenshots.
It is also recommended to visit the osu! forum post, which is linked below.
These are in the 16:9 version, but not much changes between this and the others.
Assets used on this skin which were not made by me.
