So now that 0.7 is out of the way, some possible things to consider for 0.8 besides the cliffhanger and how Orion survives:
-probably the girls finding out about all the fooling around and realising they're ok with it? (maybe too early)
-4 lewd scenes, probably Nancy, Dalia, Annie and Calypso. (hoping to keep on the same level as 0.7's, then we'll have Dalia and Annie's first full sex scenes)
-the mistery of the Island of Lost Souls
and a shit ton more..
but for those who play with pregnancy content enabled (i mean, there's no point not to) it's still, unfortunately, too early for any of the creampied LIs to become pregnant, a good guess for an estimate in my opinion is maybe on or after 0.10.
