Yeah! Thankfully saves are in their own separate location (and you can even transfer saves between PC and Android if you wanted). I hope everything goes well for your friend though o/
So far there hasn't been an official guide or wiki of sorts. The in-game journal kinda acts as the guide, in a way. We have discussed the possibility down the road.
Some choices do change the dialogue and sometimes scenes, but ultimately your choices don't result in a game over or such.
not to worried about a game over or anything, but when trying different dialogs with Rae during the intro sequence, I found one that would increase either intimacy or lewdness depending on the choice, but like... almost directly after that, she drags you to the dream realm and seems to reset those values once she realizes you aren't some big shot magi lol. And some of the other stuff being said changes depending on dialogs, like if you keep telling the truth, she will admit that she was mistaken and you did keep telling her, but if you play along with it the dialog is different in how she says you don't do magi stuff lmao. It's fun lil paths like that that make me curious what choice does what, if that makes sense. And rarely do I see a wiki or guide note those little details down lol. Like putting a lil footnote in a choice section that it will change X event down the line. Corruption Of Champions 2 wiki kinda does that, but the wiki had fallen behind a lot last I played it. So older events would sometimes directly link to a different page depending on what happened.
Sorry, bit long winded, but I always find spaghetti pathing in choices fascinating to see what does what and how it changes stuff.
