Breathplay, forced pot/poopper inhalaton, breathplay...

The subject could have certain areas that are more effective in tickle torture. Stuff like maybe their toes are more sensitive then their furred sole or pads? Vice versa? Their feet are so so but their pits are just too much for the to take? Just fun ways to find what spots make them squirm and plead more. Randomized spot finder. Maybe certain areas get more sensitive when other things are done/applied to them (oils, brushes, etc)

A menu that can be pulled up to quickly teleport to important areas or access important features to allow a simpler experience. This menu would only be unlocked after completing the tutorial (or in free play) and would include access to the shower, client selection, and research screens, along with whatever else is needed, and have buttons to teleport to each client. This menu would likely be the default screen when pressing Esc.

Fek, I think you should consider about start adding new species to the game. Maybe one new species per update isn't much additional work?

Boob swing and jiggle needs to be enhanced.  A big boobed character mounted in the stock rack should have her tits swinging all over the place when being fucked.

For added decoration and for a practical purpose:

Some NPCs give you a limited tutorial on what to do in the lab. However, for further and more detailed instructions, the player can go to a small library (or in your office or an employees' lounge instead) to read up on instructions on the game. Plus you can read about how research is done, the 6 elements used for research, and a catalog of how much of an element is normally found in each species, such as horses, bovines, and deer having much more equimine than canines and felines, but have less felinium or caninium than canines and felines. Birds, dragons, and gryphons should have much more avium and scalium than mammals, but have less of the other 4 elements in comparison.

Or planting your face and moving around in the subject's boobs or chest.
