A few suggestions:
- Maybe add the function of creating custom characters for the recruiting at one point in the future.
- I know it would sound scandalous, but maybe add a purchasable upgrade that allows same-sex mating to produce offspring. Maybe the option becomes accessable if a certain threshold is passed (something science-y or something).
- Improvement of the scrolling down in the recruitment list, because it is sluggish as all hell!
- For the upgrades, maybe an option that allows bulk purchasing could help reduce the mouse button abuse. My mouse laments the constant clicking...
