Here's a theoretical question, Since all members of this alien race have the properties of their namesake element, is there a possibility that Alloy Girls exist?
I know this is a silly question, due to the fact that all of the individuals of this race resemble human females, and I highly doubt that there will be Futanari content in the game.
Overall, a great Demo for the gameplay, but not for understanding how a race that are literally living metal statues would reasonably work,
