Re: Sakurahime (in progress)
VH had the ovulation system with sleeping passing time and children as items after birthing scene.
Other World Quest had an odd system where pregnancy was random if they came insideand pregnant women would get a power up but when they gave birth (with a scene) lose a little permanent HP. The game was easy enough they could have a lot of kids without issue though. Again, kids were an item
The Sexout mod for Fallout New Vegas had time pass more like OWQ, except it was seconds not steps. Sexout mod has you set your fertility, and even how long one stayed pregnant (1-300% of time) with 1% being several game days. Being pregnant made you less able to carry weight or fight (opposite of OWQ) but you could just sleep or wait to get through it. Being real time the Courier eventually gets to the point where she can't hold it and falls down and births...the baby (human, mutant, monster whatever) then follows you around though they are not very useful.
RyonaSaga had pregnancy basically as an attack which if it proc'd the girl would eventually birth a new monster...which might be in a later fight. The monster joins the other monsters fighting. It was very simple, not an rpg just arena/dungeon
Those are the best preg games I have played and how they dealt. I loved VH's system but hate having to keep sleeping at the inn to progress pregnancy. something more like the other three where time/steps/turns later the baby comes would work for me.
Thanks for the detailed report on pregnancy systems.

I was thinking that if o-dobi didn't use birth control and have sex would have a chance of getting pregnant. And the hornier o-dobi is(as in the higher her lust/arousal) while she has sex the higher the chance of her getting pregnant.
If she gets pregnant, her mobility would decrease and she would be more easily aroused maybe but there will also be something else good about it(not sure what just yet) and she would give birth after a certain amount of time has past(not sure just how long though).
she'll warn you when she thinks she's about to give birth and she can give birth just about anywhere(though it can benefit o-dobi to have someone else help her deliver the baby and o-dobi is defenseless while giving birth.).
After the birthing scene, her child will probably be like an item that she can keep in inventory, hold/carry in her arms, breast-feed, set down, give to someone to take care of for the moment(or a childcare center maybe), sell(if it's a boy) or abandon(by setting the baby down in certain places and leaving).
(I would like to make this part after she gives birth more complex, so I'll work on adding more to this idea.)
Thanks again, I think I'll avoid forcing you to sleep at an inn to give birth(I'm thinking it'll be time based), though maybe that could be an optional way to cause her to pregnancy to progress faster(since it makes time go by faster).
I didn't originally have issues with the movement speed on my first play through, but after being found out and starting over from the start a couple times, the slow movement eventually got to me. Boredom from slowly moving down the hallway as punishment for failing the little sneaking session discouraged me from trying again.
And again, it was completely smooth. Just really slow, especially when it looked like she should be moving faster given her animation.
Oh, well the demo was originally intended to be really short and take no more than 10 minutes, sounds like you just need alittle help with tactics. When you start the part where you have to guide the winged-girl do the following to complete the intro:
1 - walk to the right and you'll see the first student, she'll automatically leave as o-dobi talks.
2 - continue walking right until you meet the second student, when o-dobi talks choose the following choices to get pass her:
"Talk to her" > "Shouldn't you be in class?" > "Why not?" > "Don't worry, he'll probably say yes."
3 - continue walking right until you meet the next student. For this part you and the winged girl just have to avoid standing in their vision oval(you should only have to avoid 2 or 3 students).
All the students will walk in the same pattern over and over again, walk pass each one when they are facing the north(that's when you can see their backs). After you pass the first student, take the first path to the north and you'll only have to pass one more student to get to the restroom.
Make it to the restroom door and congrats you've completed the intro.
As for running, it's on my to do list and again it might be in the next demo if I get around to making new walking and running animations that I think are good enough(I would like the hair and clothing to move as well), though it maybe quite awhile before the next demo if I try to add everything that I want.
