Hi friends, I have another major update for you all :)

Windowkill now has full modding support and asset customization!

Window themes, cursors, backgrounds, skins, etc. can all be customized easily in the files. And for everything else, modding allows for unrestricted changes to the whole game!
Read more about how to customize Windowkill here!
Along with the update, I’ve also included the game’s full source code. Not only that, but I’ve open-sourced all of Windowkill’s original assets as well! Read all about this in the link above :)

If you want help with modding, or want to share your creations, feel free to join the discord!

(Also I’ve given the game a discount along with the update, maybe gift it to a friend if you already own it :)
