I would like to report a slight bug. It's nitpicking really, so you don't have to bother about it for your next update, RedEye.
The animation of Zu with Big the Cat in the gallery is quite off-centre. It moves substantially on the right when it triggers compared to other animations.
I think instead of making a whole pregnancy mod it would be easier to add a birth animation after defeat and impregnation in the normal mod. And maybe adding variety to babies characters given birth according to the enemy who defeated them. I know things I suggest are not easy either so please don't take it like I'm pushing you guys. I just wanted to drop some suggestions.
Well, pregnancy mode is not necessarily about birth animation and getting pregnant as we have fertilization animations and even some enemies births like the spiders (which are both awesome, I'm so glad for these, awesome job from Redeye Samurai).
It's more about having the same animations and game than the original but with pregnant sex, which imply that the girl are already pregnant. It's really cool to have the options for pregnant sex and Redeye Samurai choice to implement it as another mode is probably the right way to go. One mod with impregnation in various cases including all the good ideas you mentioned:
- impregnation, which is already here with the ovum/fertilization animation upon the right type of defeat/life loss;
- birth animations, the spider's example is perfect. Following your idea and what Redeye has already implemented, I propose that the ability to make new enemies with one attack guaranteed should be kept for the Spider and the Jellyfish. But when other enemies makes the player character pregnant (fertilized ovum animation), specifically THEN you'd have a new enemy spawning as well along with the birth animation. Or if that's too much, too redundant or too spammy for example, then just the birth animation without a new enemy spawing would be already really good.
What do you think Redeye Samurai? Feasible? Or maybe you envisioned something else on that topic? Of course, that should be something to add later when you're satisfied with your progress or when you've finished with everything else, if you feel like doint that. You're already doing so much good work. Like sonic 3 mentioned, to implement these ideas would not be easy, so do what you will with them, just suggestions.
