Three cycles since fecundation. The pharates can taste our thoughts. Their pupal minds yearn for mothers’ milk.
You are sending commands to a parasitic, insectile entity, and there are a number of steps it must complete before it can successfully parasitise the host. Your task, then, is to figure out the correct order for the steps. By turns icky and sinister, Eclosion fits well in the Ectocomp
The puzzle is aided by informative failure messages, but even then, I took many turns to figure out a vaguely correct sequence. There is no question of error.
The writing in this game is deliberately wielded as well: the language is florid, like that favoured by Lovecraft, but terse; a tally of the casualties (or the pharates you fail to guide to eclosion) reminds you of the consequences of your clumsiness. This is body horror the way I like it.
