Ranks are out of 299 unless stated. From the comments on the entry:
Younger unicorns may not remember it, but I was there to witness the atrocities that yellow committed on my nascent herd, and the only punishment for such a crime can be aggressive pyramidical expansion! (Dan Prince)
The whole isometric view is cool, reminds me of populous, the select reminds me of C&C - so a really fun mix. You've managed to pack a lot into 13k. This is the kind of game I could play for hrs. (picosonic)
The generated terrain looked great, the camera controls worked well, and the procedural graphics came out really well! I also enjoyed reading through the source. (Dan Prince)
What I really like is that I can just lie back and play this with only one hand, no keyboard needed. The color palette and the whole game are relaxing. (JustGibas)
I like the world and the AI is pretty good, it gave me a hard time. ... Really good job for such a tiny game! (Rubikou)
You lead a herd of unicorns across a continent that has been drained grey. Ground comes back to life wherever your unicorns walk, in your colour. Living ground is your income and the only place you can build, so growing means spreading out across the map.
One to three rival herds are doing the same in their own colours. Where two herds meet, the ground bleaches back to grey before it changes hands.
You win by holding enough of the continent, or by destroying every rival grove. Both conditions can be turned off before you start.

A grove trains foals, which are fast, cheap and the best at spreading colour. Losing every grove can lose you the game.
A stable trains chargers, which are slow and hit hard.
A spire trains prisms, which shoot from a long way off and bring ground back to life around themselves.
Chargers beat foals, prisms beat chargers, foals beat prisms. Attacking from higher ground does more damage.
Buildings need a flat two by two patch of living ground you already own. Each one you add raises how many unicorns you can keep, and each costs more than the last of its kind.
The lobby lets you choose the number of opponents, how large herds can grow, the speed of the game, how hard the rivals play, and which victory conditions apply. It draws over the map you are about to play, and a new world can be rolled until you like the look of one.
