Kind of ironic that male character got taken out. I still remember near the end of EroDungeon's development, the creator made a point along the line of this new game letting the player be a male character as their own self-insert.
P.S.
If you want a monster person catch/management game with male and even futa characters, I would suggest [Portals of Phereon] by Syvaron if you haven't heard of it yet.
Well... from a game play mechanic perspective I can understand why male as a possible gender got taken out. Unless Mado was interested to do some possible bishounen/trap/yaoi action with this new game (which I assume they don't judging by their previous games), adding only one in-game male character to represent the player would only limit how much can off springs be produced with one character.
Could have been an interesting idea to bottleneck the player's manpower/economy growth if a game is set with only a single male character to impregnate a vast pool of randomly generated female characters. But I'm guessing in the end Mado didn't want to turn this into a 'plug in the math formula game', so that idea got dropped very early on during development.
