This game leans to the 4X genre, where you have to expand your territory and the such with your duck army.
You will first start with 5 ducks and yourself, in a small nest. You can order them around to look for food, materials and even patrol around for pesky predators. Expand your nest to hold more ducks later in the game.
There will be random predator attacks as well as ducks that will be migrating to your settlement. You can explore the map to meet other duck settlements and you can interact with them and befriend them using a "dialogue" system involving lots of quacking. Inspired by the game Spores, in their early stage, you'd have a similar interaction system with entertaining them either singing, dancing, cultures or impress them with your military skills.
As you progress and grow your lil duck kingdom, there will be technology as well. Later you will advance as a intelligent being using armors to defend yourself and such to defend your Empire.
Encountering different creatures, like wolves and snakes, you can learn different techs. For example, when you killed a snake you'd be able to use their skin for armors. When you defeated a wolf, you'd have the ability to actually mount them.
In the end of the game, you'll conquer the world with various ways like diplomatic way, with culture, or with military.
