Hmm. Okay, I would need some more info on your gamestate so I can help you. Add me on discord if you're okay with that (alex_grim), we can look into a not so spoiling hint I can give to you!
Funny story. (Not really.) It turns out my trackpad settings were keeping me from clicking while a key was pressed. Once I turned that off, things made a lot more sense.
Anyway, that's how I destroyed the entire world and got ending B. Kind of a bummer. Trying to decide if I have the energy to go through it all again...but it's very cool in any case.
