I’ve been having trouble with the Species layer. Reaching a significant amount of species above e18 takes days, and switching to easy mode hasn’t quite solved this issue. Surely I must be missing something.
At the moment I have 4.5e34 species with 2 Chromosomeless, 2 Nucleusless and 1 Energyless completions, 7.3e215,451 genes, 2,018 chromosomes, 88 nuclei and 129,065 tokens II.
Maybe I could try a different animal achievement button combination for challenges.
