there should be pauses in the dialogue with the subject, that is, as if time stopped, so that the robot can explain without being interrupted by the subject

it would be cool if you could make any music play while interacting with subjects or just relaxing

Exactly what it says on the tin. The ability to relocate a subject from one rack to another within a single session would be a nice and simple quality of life improvement.

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.

Hello, I would
like to know when the option of knotting in the Rack 2 game will be
available, or if it is already available how, it is possible to do so.

Thanks in advance for the information.
