Of course the one time I come here to look for an answer the search is disabled for maintenance and rebuilding the index. I'm not sure why it took me so long, but I fired this up for the first time today, and been enjoying it. I'm trying to figure out my Save Management and having two protagonists potentially makes things a lot more complex.
By looking at the '_dating' variables, it seems that Ian has 6 LIs, Lena has 9, and an additional Ian/Lena path. I guess what I'm trying to figure out is, do I need to have a save for each combination of who they are dating? If so, that's a staggering number of saves/playthroughs to work through.

If it doesn't affect the overall story or interactions between Ian and Lena, then I may just finagle singular playthroughs as for each LI.
