Camouflage from predators. See without looking. Lead your children home. Evolve.
You are a tiny creature in a dangerous world. Lead your defenseless children to safety. Adapt to new predators each level … until you evolve into a different species. Survive in an evolving environment by morphing between light & dark forms to camouflage from your predators. But be careful: you won’t be able to see yourself either. Lose the ability to see where you are, and learn to feel & know where you’re going.
