MIRO Demo: Update 0.1.8

Hello everyone! We've been working tirelessly to finish MIRO's main missions and content. These things also affect the current demo version, so we've updated our current version with a bunch of fixes and functionality! Here's a quick overview: - Player can now crouch, making less noise - Creatures interact better with each other, carnivores of different species can now fight each other and some herbivores will defend themselves. - Balanced planet progression: we've removed some bloat and made the initial planets more interesting by increasing the number and types of buildings that can be found on them - A lot of other fixes that I honestly don't remember right now :( Let us know if you run into any issues or have any feedback! Enjoy your travels :)
