put more states of pregnancy (larger), other types such as eggs, penalties based on the size of the belly and species of alien such as reduced movement or less strength.
for when it is advanced, have the option in the genetic modification laboratory while it is gestating and consequently they are more extreme states but with great benefit when the gestation ends with a stronger interspecies hybrid although this could only be balanced if the enemies have certain degree of difficulty. and if he also puts a failure factor so that with a percentage the hybrid instead of being stronger is weaker,
Great job, from the little I played, it lacks more content and is full of bugs, but it's normal in the alpha version.
When it comes out I hope I have the money to buy it xd
ps: let my imagination run wild writing this crazy suggestion here I wouldn't feel bad if it's rejected due to the limitations of the rpg maker engine or because they didn't like it
It is my humble opinion
