There are so many ways to die!
Ferrovore - complete the microbe stage using only rusticyanin
Die, die again - die within three seconds of respawning
Et tu, Brute? - be killed by a member of your species
Strong, independent daughters - reach the aware stage with exclusively asexual reproduction
Icarus - die from fall damage as a flying creature
Diggy diggy hole - die by burrowing into magma
Mistakes were made - be killed by your own toxins
