The game idea itself is so original too!
It's a very simple but gorgeous 2d top-down "strategy" game. It has calming music and a soft colour pallet.
You control these flying boids/bird things by ordering them to conquer other "planets". The goal of the game is to conquer all planets on the map.
Each planet you own periodically spawns more "boids". Every planet has a number which describes the amount of boids on the planet.
The only actions given by the player are orders to move boids from one planet to another. If the destination planet is an enemy planet, the boids will attack. If the destination planet is friendly, the boids will combine in forces.
Planets have trees that sprout, and the boids are like leaves that sprout from the trees.
I think once you beat the game you unlock a dark mode.
Does this game ring a bell to anyone? I now want to play it really badly again :)
