We finally came up with a longterm motivation for our game Niche!
After countless brainstorming sessions, spread over the duration of half a year, we decided on a setting: Islands. Inspired by Darwin's finches we send our animal species across the ocean and let them start their population on tiny "Tutorial island".
On this little island, the two start animals (Adam & Eve) can start expanding their family.
After a few generations have passed, a piece of driftwood lands at the shore. There is only space for a few animals. It's a hard decision which animals to take to the next island, though it's always possible to come back to the previous islands. The main goal of the game is to inhabit all islands that exist with your tribe.
Let's have some more islands shapes :D
