ATM I'm pretty nonchalent about this update being good or bad. Which could be supportive or detrimental to the game.
But I do hope for it to suceed, so this are some recommendation based on 0.4.1 update.
Recommendation(Not a demand, just giving out mine or other's opinion so that if you have the chance, to flesh out breeding farm more and make a more defined and unique monster girl genre game):
When I first played it, I had 0 clue how to advance the day through clicking the arrow button, once in a while, some newcomers also encountered this issue.Maybe you could update katelyn's tutorial. Also maybe add a day,night no. of turns limit. Like you can interact with 3 things before it moves from morning to afternoon etc. This could give players more effort to plan their time well and not just use the arrrow to skip time quickly.
As stated by an earlier post, the gender of the baby is entirely dependant on the race and gender of the parents. This meant that we will constantly have female elves, which biologically makes no sense.
No issue with cece and Nu being barren, but maybe one of the plot points could be that one of them, prob cece, loves the mc so much that they start ovulating and become fertile but only to the mc.
I don't know if you could sell dragons yet but this applies to all monster that could not be sold: General: Donating monster back will increase alliance trust -> might increase affection with the queen and/or the girl representative of the monster. Elves: maybe later on, we can sell elves girls as there is an over-abundance but still have to donate elves guys. Dragons:Increasing alliance -> gets higher ranked dragons.(Higher ranked dragons has more human features and less lizard features)
Monster girl traits(not refering to the inheritable traits): One thing that makes the monster girl genre unique is it's trait. I personally think club bifrost is it's best example of a monster girl trait. Basically monster girls are like races and a good game of that genre should focus on it's quirks and cultures. Maybe implementing some monster girls quirks to make them unique and/or improve the ingame demand for selling diff types of monster girl. For example: Having a horny season(on in bifrost's case, full moon), it increases the preg of most of the monster girls and could potentially introduce horny scenes. Dragons,mermaids can't give birth immediately but lay eggs(which could be sold) and takes a while to hatch. Cow girl being able to be milked. Elves having a harder time to gain affections and may not want to mate with other monsters when they have low trust/affection. If males don't fuck/ejaculate for a while, they will fuck and potentially breed with any females. Monster girl has different tit/ass size, while monster girl has different dick/body size, which customer might demand certain trait of. Same race has a high preg chance then mixed race. Some races might not like breeding with other races,(e.g. elves hates breeding with orcs). All of this traits provide players with more motivation to experiment breeding. You could also maybe borrow some idea from Club Bifrost:

People wants the story to have impactful choices. That the main reason majority have issues with rika ntr scenes. I had no issues, despite being a person who dislikes ntr. I can't advice to follow or not and it should depend on team bieno if they want to commit to an easier but must be more consistent linear storyline or a more complex and more flexible complex multiple choices. But if you are going for complex:
-Maybe if you guys want to appeal to both ntr and non-ntr(not recommended if you guys aren't swamped), you could have a horny meter or smt to that extent. If the player ignores/haven't fuck a particular girl for a long time. Then it triggers a ntr scene.
-Affection stat for the girls/boys. Reaching certain stages triggers a quest. Then if two or more girls has reached a certain stat, you could pull stuff like the cece and rika threesome quest.
-Date monster girl/boys with high affection.
-high affection girls/boys can be convinced to work as breeders.(e.g. rika loving you and you selecting the you are fine with her fucking -> she becomes a breeder)
-individual girl/guy ending scenes and/or harem end
-fuck guys(we only have poe) n I'm a straight guy
Including more human races? Like maybe asian or black or other human races but live in-game with their own culture(Not because of woke diversity, but because of well, races and interbreeding).
Include more fantasy races? Dwarfs, goblins, orcs, idk trent, golems
Include more fantasy classes?(with their own quirk like maybe hiring whores to breed with the monsters but lead to std idk) Mages, warriors, sailors, blacksmiths
I DON'T think having a female mc is worth, despite the complaints/demands for one. As of now, the story is linear and having a female mc would add more effort, might break/limit the story (e.g. Rika addicted to wolve dick but as a female mc with no inhuman dick, she can't sastify Rika).
I can't think of anymore atm, but I could add more later on. Basically, good luck and hope the team won't be discouraged or overworked. And maybe in the future, breeding farm could be a game that could elevate the monster girl genre. I also believe the ppl here are just criticising the game as they atleast care about it to a certain extent. I may not have spent a lot of time on f95zone.to but I think if people think a hentai game is shit or poorly, they won't mention it in post(excluding mtl hate)
(edit)I think as of now, prioritising on making the breeding mechanic(not the sex scene) is the most important. I think the breeding should be fun and constantly engaging. Making it more versertile or being able to meet certain demands(e.g. I want wolfman with selfish trait at 900 coins ), motivates us, the player to continue on the breeding, instead of no money, search bulletin board, see cat girl, find weaker secondary cat girl, use cece to breed, sell cat girl profit, rinse n repeat tillno energy, click arrow to advance next day and if still have less money, rinse and repeat. If have alot of money, do quests,finish update's content.
(Edit) The church influence might also help with the money issue. The game is easy to earn money, which means half the time, you have no monetary motivation to do anything. Maybe the church might rise or low taxes(and we can see it at the plaza). The church might also increase the tax based on your profits for the month. You can also donate to church for infrastructures and gets bonuses for the farm. U can also donate to make the church like you more and lower the taxes or give you certain priveledges like able to visit the central church, visit the castle. The church(or any other factions) could also be a constant antagonist that would trigger certain events like letting one of your monster escape cause your barn's security upgrade is too low etc.
(Edit) maybe you could go for a dark route and you could abuse your monsters. maybe you could let your monster fight in the arena and its stat is based on the breeding stats. Winning in arena might give you more goal, infamy, some treasure that affects the game, like upgrades, and maybe you can date a guy/girl aka a new story dating route
