Things like eyepatches, customizable collars, earrings and piercings, bracelets, necklaces etc.

an option for a genital "slit" that the penis will slide out of when erect, as often seen on reptile/dragon, bird, and sea-creature characters

Can be penetrated like a vagina

it'd probably be hard to implement, but i think it'd a cool touch to add some "physics" options, where if the penis is particularly small, it can still be penetrated while erect, or if the penis is too big it won't fully retract back into the slit while flaccid

There should be a category for humiliating the subject while forcing them to cum. as its own specimen I mean, since there is going to be mind control you hypnotize them afterward to prevent any ill effects of having been essentialy broken during the session (wether they remember what happens or not)  

Lots of Bras, Panties, and Swimsuits to be worn

I would like to have the ability of letting a tentacle makes its way through the gastrointestinal track, starting from either end, and that would be pretty cool if this game has that feature.

Inserting a characters muzzle into another's pussy/ass

i think you should add in-game cheats like in rack 1 and allow mod support

Sorry if this is the wrong place to put this, this and patreon are the closest things that Rack 2 has to a forum.

I've subscribed to the Patreon and I'm trying to run the latest version of the game, but it's not working. When I boot the game, there is a brief loading message that goes too fast for me to see, followed by a black screen with a tiny symbol in the top left corner. Any advice?
