This is a slice of a game I always wanted to make - I wanted to make a simulated ecosystem with creatures doing their thing (eating, fighting, making babies).   There is a lot of neat logic in the animals, they flee and fight and f-eat things.

Ran out of time with making the map interesting, there's a quest if you want to try.  

Although it mostly works when networked, I would try it single player first as there's plenty of bugs already.

Struggling with making the whole thing in my spare time, but I'm sure I'm not the only one!  I'm obviously not an artist, mapper or sound designer.   Models and sounds are either from sbox or from my collection of purchased assets.

You can hit R to respawn if you die to the fearsome ducks.
