Game called breeding farm doesn't have a pregnancy tag? Seems right.
The ban hammer of many sites are looming over breeding games with "pregnancy" tag on it. Since it implies giving birth to smol offsprings and made the offspring a further potential breeding partn-*whack*
It's exactly why many games in this genre tend to utilize loopholes such as eggs, magic, time and space womb, auto-legal age birth and the likes
i mean, they could still utilize pregnancy state and THEN use the loopholes above but maybe the dev feels it ain't worth the risk of being put on their income source's watchlist
