So, I've checked this out for a little bit, and I have a couple suggestions.
First of all, like others said, it'd be good to have a way to "discard" unneeded test subjects, as I got myself into a spot where I had a bunch of mismatched subjects and couldn't accept more to actually finish any quests. This could easily be fixed in the short term by just making the "internal request" for more workers repeatable instead of a one-off, since it accepts any non-human girl.
Secondly, this is somewhat of a problem that branches off my first issue, but the starting set of quests, that being the Horse farmhand one, the Mission Statement sheep one, and the Cow one, all take 3 subjects to fulfill, which is exactly your capacity. I think it'd be better if you had at least some capacity to work on two things at once at the first stages of the game.
Third point: The game was quite unclear on what exactly the qualities of sample even do. I would assume that they increase the number of mutations that any given serum provides, thus increasing the chance for a full transformation (presuming it was even intentional that I had two subjects injected with a Chicken mutation that just... stayed human until the dose wore off), but that doesn't seem to be the case. Also, you aren't told what the three stats even do. Presumably they aren't implemented yet, so I understand that part, but to get a bit of a sneak peek into it would be nice. I would assume Combat associates to Guarding, but I can't figure out whether Production or Social would go to Agent or Scientist, since neither seem exactly fitting.
Fourth point: There are too many different DNA samples in the Farm to get so it becomes irritating waiting for it to get you the right ones of Cow, Sheep, or Horse. I get that it's tempting to show off all the features you have, and that is all well and good, but in this case, it gets in the way of gameplay, as the sample collection not only consumes time, but also money. Not to mention the fact that any experimenting with transforming any of these extra, unneeded mutations, just eats up one of your observation cells.
However, I can see a lot of really good ideas for features. For example, the different morphs having different stat increases is interesting in the context of mutating your employees, as picking the right one for the right job might increase their productivity. Also, the fact that you can hypothetically mess around a lot with the "genes" as it were, and try and splice them, makes me quite curious for the future of the missions, like trying to make an egg-laying cow, or an extra-strong chicken. I can imagine in the late game having to splice the right traits together to make a cockatrice out of chicken and snake DNA. With enough polish, this could be up there with Transformation Tycoon for those more interested in the furry side of that game.
Also, minor gripe, but I find it odd that the Egg-laying can develop before the subject becomes female, since it mentions ovaries. It calls into question what exactly the judgement is on whether a subject is male or female, and the "masculine" and "feminine" traits complicate things further, since they aren't really defined. Do they both mean, like, someone with traits from both genders? With feminine having more female traits than male and vice versa for masculine? Or is it more like "staying the same sex as originally, but with more feminine/masculine traits" like a tomboy/femboy? In either of these cases, wouldn't any gender transformation end up stopping on at least one, if not both of those, during its course?
I'll definitely check this out again if it updates, but for now, I'll be waiting, and I hope you appreciate my feedback.
