A little preview of something that I've sneaked into the build before alpha - alien plants! Biomass (which is one of the five resources in Isomer) previously could only be collected by looting killed units, but this method forces you to do a lot of fighting and each body only yields a small amount of the resource.
Compare this to stone or mineral resources which are all over the map and can be mined relatively quickly and easily. So despite being the scarcest resource, Biomass is as essential as the others particularly when you want to mutate your workers into other specialist unit types.
So, I've added the ability to craft terraforming blossom trees.
These trees spread spores around them creating and growing biomass plants. The plants start off small, but grow progressively larger over time creating whole fields of biomass that can be harvested by your units.
