Didn't see that one at first. I've also made all elements dark, not just the background. I guess people can choose if they want to.

Spent a few hours last night making this dark theme to not have my eyes bleed late at night.

All pages should be working as normal, just with different colors.

All you need to do is install an extension named Stylish - Chrome DL - FireFox DL.

Then you just click the extension icon while being on Over.gg and it should appear. If it doesn't appear, you can download the theme from here.

If there are any issues, feel free to comment and I will fix them.
