Apparently, he will keep doing updates every other month. You can read the full message on his patreon (without being a patron).
There's still many things Sid could add to this game that would give it an extra star from me.
Aside from adding animations to the sex scenes (not sure if he knows how to do that),
then simple additions could be:
- closeup scenes so we can see the penetration with Megan and Susan
- titty-sucking (not once has he latched his mouth onto those glorious milkers, which is unforgivable!)
- fingering (it's been suggested that he has done this, but no visuals from what I've seen)
- anal (it was subtly suggested by Calvin when he has Megan in the bathroom and asks her to bend over)
- toys
- ball licking
Plenty more story to tell or add to, if Sid chooses to do so.
