I actually am working on a sequel to this game right now ^^ and I always take into consideration feedback. I think this game ended up with 17 total lewd scenes scattered through it but more is always better. I do want the games to stand on their own without the lewd content so I sprinkle them in when they seem appropriate. I am, however, hoping to include more in the next game with some more interesting variety. Rollback function is another big feature request that I'd like to add. That and saving anywhere instead of checkpoints are two big requests. I've got the programming done to save anywhere, and I think I have a good idea on how to make rollback work nicely so with any luck they'll both make an appearance. Mode change would be nice too and could easily be added into the pause menu. If I get some spare time I might update Chasing Tail with that feature anyway. I do have a pending update with a few bug fixes and an 18th lewd scene prepped to be added still ^^
It's on my to do list for sure. I've got a big outline for the game and all the paths started but needs more work and then I'll post it up online somewhere or I guess I could even put it in the game itself. I know the flowcharts don't give all the info but hopefully in the meantime they'll help a little.
