We built another ecosystem. This one has sprites.

Nine years ago you took an interest in a game about polygons eating polygons. That is still the largest group of people who ever have, and we have never quite got over it...

We have built something new - Now instead of polygons it's sprites eating sprites..

Captain Contraption's Safari Park is a park management game with a properly simulated ecosystem underneath it - no fences, no enclosures, no way to tell an animal what to do. Every creature is an individual now, so herds have stragglers and wanderers. Territories pass down through generations. Creatures sleep. Fights end in routs and chases instead of always ending in a corpse pile.

The playtest is now permanently open to everyone. Free, no invite, no deadline.

If you know what a food chain looks like just before it falls over, we would really value your eyes on this one.
