Ovum

OVUM is a journey down a totally vegan rabbit hole, because you get to become the mind of a colony of plants with the unified will to break stuff.

Certain things left behind from an extinct species have been corrupting the soil from deep within the earth. As much as you need the sun, you need the soil, and so you will push your roots into the farthest caverns of lost history. You will destroy everything in your path, unless of course it's a poisonous mushroom, or a stone wall, or an exploding mushroom, or a precipitous chasm. But you will at least destroy most of it.
