The context-sensitive icons originally started as abstract elements to convey the actions the species could take, ie. hide, eat, call, warn, drink, and attack. As the gameplay team narrowed the list of actions that were essential to the game's playability, the icons were changed to be more literal depictions of actions. Below is the development of each icon, showing only four of many stages it took our team to realize the final icons (largest icon in each set). All this work did not go to waste though: our icons are now used in the current model of the game.
