Thank you so much for the comment!
I'll try to upload a video to show some tricks to survive longer. I agree the rules are obscure. In the beginning it was intentional because that's the reality of our human gut. Our science is yet to understand how the microbiome really works. But later I realize it's really too hard... sorry...
Tip: green bacteria (h-pylori) is easy to kill and cannot harm you. Red bacteria (c-diff) can be killed by the blue acid drop.
