For future updates, will our character will be able to carry multiple babies. (I hope the maximum capacity at the end of the game is quintuplets.) The strength or power of a breeder is determined by her belly size, right?
LV 4 - 6: Twins - overdue twins
LV 7 - 9: Triplets - over due triplets
LV 10 -12: Quadruplets - overdue Quadruplets
LV 13 - 15: The Legendary Quintuplets - overdue Quintuplets
For future enemies, how about Bandit breeders that roam around to breeders that become corrupted by the miasma of the demon lords floor?
