once you set the difficulty on easy, where the rent doesn't increase, the game stops being a micromanaging hell, there you can enjoy experiencing on species and making cross-breeds.
i found a great bug that permits you to get unobtainable species such as specials forms:
for the special forms + tentacle girls:
-get a species or form that has mind control,(skill that act as a net)
-use it on a tentacle girl to capture her(normally it set her as a token character when with a net)
now she's in your squad
-get her back home
-breed with her in the farm
-now the offspring can only be the special form you used, or with an exeedingly small chance, another tentacle girl
-to make more tentacle girls just breed two together
for the psychics:
-capture her with mond control
-get her back
-fuck her/ get fucked by her in the sex tab in home
-with a small percent chance, you'll get more, it also works with another psychic
with the first method, you can make an army of god special forms wich, if breeded enough, can make the most dangerous army ever existing, with stats going sky high.
for example:
lily, god form
ap= 15 apreg= 11
hp= 354 mana= 662
armor= 8 lustres= 5
strength= 44 magic strength= 48
lustdmg: 15 atkCost: 2
skills: mindcontrol, timestop, lightningstorm, teleport,
ps: don't forget to empty your farm before mating the player and the tentacle girl, it leads to some bugs that makes nothing happen
EDIT: i have the 6.1.1 version, tell me if it still works
