Well, I was mainly concerned with building on everything that was originally in the game. Mainly the story, characters, enemies, items, levels. But with reworking the game from a beat em up to a platform game. Making most of the sex animations more detailed, adding more challenging boss fights, puzzles, etc.
I'm not sure. I haven't thought about adding online multiplayer yet. Once I finish what I want for this mod I'll think about it some more.
In general, the jump in the story will not be some long period from the capture of the main characters to the ship to their escape from it. so it is likely that from the capture of our characters will be a period of several months after which they will plan to escape from the ship.
It seems to me that it could take quite a long time, just as if I were creating a new character. Although I want to add some elements from this character to the original tails look.
Not all of them yet, the animations with Zeena take the most time, as they are some of the longer animations in the game.
Ehh... not so good, unfortunately. The last projects I had to do from school took up more time than I thought, so work on the mode slowed down a bit.
