There is a way to increase the player time, but that would require using UABEA exporting and reimporting a file.
First backup the file data.unity3d, it is in your monster black market root / monsterblackmarket_data folder, either in zip or another folder, id reccomend another folder. download UABEA, hit file select said data.unity3d (i keep 3, one in the file to be used, one to modify in a side folder, and a vanilla backup in case things go catastrophically bad that i have to redo everything.) Hit the data.unity3d that you wish to modify, it will then ask to give a new name, i keep it the same but have (1) added, i then move the original to be used as a vanilla backup. Something about it being packed etc. Idk when that triggers but keep that in mind.
Once you open up the unpacked version (if it even happens). you should auto default to globalmanagers, hit info. In order to save yourself some time, go up to view, then filter, or CTRL-E, deselect all, then scroll down until you find TextAsset, click it to select it, then hit the X for the type filter popup. I then sort by name but thats your choice, then i go down to PlayerCharacterData, highlight playercharacterdata, then hit plugins, export.txt, export it where ever you want. Open up said text file while keeping UABEA opened, preferably with playercharacterdata still selected (dont need too, but saves steps), Once inside your Text file, You should see a List, with conception rate sextimelist skin hair eye color, and 3 more for body characteristics. Idk what you can change safely but i have it working after modifying conception rate, sex time, and skin color, i turned mine to purple and that would look like this "m_SkinColorStringList": ["#BB00FF"], . Outside of that, change the sex time list, to whatever seconds you wish for (i originally chose 120 but that took forever even on 5x, i think default is like 35 ish maybe). Once that is changed save file, then go back to UABEA , make sure playercharacterdata is highlighted/selected and then, finally hit plugins once more, Import .txt and make sure you import PlayerCharacterData, for me its full name is PlayerCharacterData-resources.assets-277.txt Leave the name as is. Once you import, Hit file then save, close the assets info screen, then hit file and save again on the first screen that comes up when you start up UABEA. Now, transfer the data.unity3d file to MBMRoot (what ever you name the root folder, where the exe is at) / MonsterBlackMarket_data folder, overwrite the original, and you should be good to go. Right now i tend to just edit the data file directly in the MBMdata folder, and just copy it and move it whenever i make changes i think will bork it up and reset my previous progress.
Long wall o text for instructions but i figure ill make it as detailed as possible for now. You can do the same thing for Goblin, Orc, and Werewolf, i think you can do the minotaur easily but the salamander i think its annoying to locate. You can change the breeding time for goblins orc and werewolf as well.
If you want to modify the females, the files you wanna locate are DragonianData, DwarfData, ElfData, HitsujiData, InuData, NekoData, UsagiData. You export, import the exact same way as playercharacterdata. Additional information for those who may want to know. You can select in these text data files, hair color skin color (usually hair color is random), change their maint price (i like to jack this number up to increase difficulty since, end game is simply millions of moolah with nothing to spend it on). Growth time, milk production rate.
Most importantly (for me) you can change what breast sizes are available, and the chances of them. So if you are not using the tits mod or complex breeding, you can change this. What you wanna find is "m_TitsTypeChanceList": [0.01, 0.99], "m_TitsTypeList": [3, 4], I already changed this, but if you select this option, it makes them have a 1% chance to have large breasts, and 99% chance to have Huge breasts (vanilla does not allow breasts this big on normal sized units, and 1 or 2 of the small furrys). So if you want to have huge breats on humans, its available in the game, you just have to change the settings for each of the girls Data. Now understand that the [] is an array, so if your titschancelist, has lets say, 4 options, then the titstypelist MUST have 4 options. It will error out if you screw that up. But i have had success having 2 options in each folder, i have not had much luck with only 1 option. Also the HugeTits (4) are basically the largest complex breeding has available (its 5). since complex breeding added the (0) flat. well 0 always been their but he moved it around.
Last paragraph i swear...but im bad at predictions soo... ConfigData, this one is the holy grail of some of my changes. You can make large changes to almost everything. Rest time, Seconds of day (1200 might be too much time, but its sure as heck better than 300, the vanilla, because the days pass too quickly and it gets annoying with the end of day popup, but it takes forever to get everything unlocked soooo). You can even edit the probability of escaping as well, so the girls wont escape from the top side. There is a pixyrange array but i have no idea what that actually does.
