We've just fully implemented the UI side of our mod loader, as seen in the picture above. The way the mod loader works is as follows: you download mods, any mods in the Feed and Grow Fish folder will automatically be detected by the Mod Loader and shows in the main menu. You simply have to tick a box to enable the mod and then you can play with it.
The Mod Loader is coming soon. Stay Tuned. :)
