Actual challenge runs:
- Somehow (mod?), you must reach the end of the Microbe Stage without any thylakoids or chloroplasts having been evolved, ever.
- You must live at the smallest body size possible both pre- and post-nucleus. (You play this with ultra-low MP cost.) No metabolosomes or mitochondria allowed, as oxygenation chaos means that they can be incredibly powerful.
- Bottom of the Food Chain run. (I don’t know how you’d force this.)
