What I believe needs improving:
I think this game can have potential with the pixel animations, and hopefully less AI art, I like the concept of the game. I would also like to see the character status portrait, sex scenes (just more sex positions), sound, and story get improved primarily in the game. For status portrait I do see everything, womb and ovulation status which is great and even sperm fertilizing the egg. I think it just needs a visual quality improvement but nothing much else.
If you want you could include an x ray of the zygote dividing itself (cleavage).
For the story I do hope a question gets answered like, why did the Aliens turn males into sex frenzied zombies who are clearly set to "mate on sight" for any females they come across?
I like how there's already an internal view of the penis making contact with the protagonists cervix and creaming it after, but I also agree it is too quick of an animation as some others said.
Suggestions:
This is a me thing but, the dev could mess around with adding more to the impreg, multiple eggs fertilized in one sex session if the protagonist is ovulating or has upgraded fertility or if the sex scene can be looped allowing the npc to creampie the protagonist again, lactating breasts that could be used to blind enemies or drink a charge to restore an endurance life. Get creative.
I'm sure a corruption system will likely soon be implemented. It will be a mental game for the protag to resist but not for her body, I can imagine her hips getting slightly wider to accommodate for birthing (wider hips) and increased fertility (more eggs released during ovulation causing multiple pregnancy, could result in twins or more but I'll leave that to the dev) I can see it happening from her getting pregnant many times.
None of this has to happen, but with the ideas I wrote, it could give some insight.
