awesome. If I may, an interesting idea could be to use different plant material as special ammunition to use against the sentinels or native life. such as the frost crystal slowing/freezing them, or something like that. Im sure there's a better way to utilize it but i might as well suggest it.
This is a great game and with a few updates it will be a favorite of mine. Will hostile spaceships be a thing, and how do you plan on making the plant material usable?
