I'm happy to hear you like it! One of the next few updates will have male-on-male, along with feral-on-player.
For other species, I will be teaming up with an excellent 3D artist to make an open world game, where we will add more and more species to it. In this current game, there won't be any extra species besides variations of big cats, but the open world game will be very similar in art style and play style. You can sort of think of this game as a demo for the open world game, but it wasn't initially the purpose.
Also, the next update of this game will have his models as a replacement for the current, so you'll get a peak at how the open world game will look.
I do have a Patreon page! I need to add it to my itch.io homepage, but the link is here!
