This is fun as hell. I love the feeling of nature as something that looms, something that can quite literally fall over you at any moment if you're not paying enough attention. The battle system doesn't get boring easily, as the machines can always surprise you, similarly to how animals would in real life; they behave realistically, and that requires for you to also behave realistically (both by being always on guard and by strategically thinking over the way you will face a certain machine or another using the rather limited resources you have at your disposal). A good science fiction story with genuinely interesting mechanics.
