I am confused by many things here, but mostly...
(a) Still not sure exactly how this differs from the original Goblin Burrow game
(b) Mostly confused by the sub-title "I'll Borne" which... is a contraction. "I Will Borne" or (future tense) then (past tense). Are we sure this isn't supposed to be Ill and not I'll because Ill (or sick/bad) makes much more sense for a game about breeding evil monsters than "I will/I shall" "already be given birth to".
Then again, this is Japan, so maybe that is a sentence that makes more sense in the original language.
