Why would the game have different “complexity levels”?

[AnthropocenianAge (AnthropocenianAge Arthropleura wants to give you a hug!)]

What do you mean I am not complex enough? - Become the least complex sentient organism possible while still being able to move on to other stages of the game.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

Would that just be like a brain blob thing?

[AnthropocenianAge (AnthropocenianAge Arthropleura wants to give you a hug!)]

I have no idea…Maybe? It depends on what can actually survive in the game, of course.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

If the environment is friendly enough, a player could quickly snag sapience with a brain blob thing that would barely work had the conditions been just slightly more hostile.

[domin2ktr]

I meant levels of difficulty, not complexity.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

So “more hard = more complex/timetaking”?

That’d mean the game knows at what sort of pace you completed each playthrough…
