Tooth and Tail is mostly powered by XML, allowing for easy modification of game files. Modding is fairly simple, simply go to the installation directory and play around with the files. Excluding sound files, most other things can be edited directly and will be changed upon rebooting the game. Any recommended mods or suggestions are welcome to be added in the below sections.
