The game itself doesn’t have cheats, so the only “simple” ways to cheat would be to use software to change the save file data or manipulate memory during the game execution.
I’m not versed in Android tools so I cannot advise here, but I would suggest you search around for apps that can do that, or await for someone’s answer, if anyone already succeeded. Be extremely careful with what you install on your device!
As a side note, using apps to cheat on the game on Android will most likely require a rooted device, because Android is not as permissive as a computer, where you can just open a file and do whatever you want, I’m not entirely sure, but it is very likely.
Regarding the reaction point, Leah should already react to the parasite worm scene on waking up.
