Well, everything has been said about Alex.I don't understand the hate people have for Alex. I normally hate starting with a gf/wife, but Alex is awesome. Isa, well, not so much for me. I'm still a bit behind and probably won't catch up for awhile. But I'm also behind on several other games that I play.
People love her or hate her and even some people who love her don't like her hairstyle.
For Isa it's a bit unfair, as her character building isn't finished yet. Which is clearly a mistake on my side.
But I think it's clear until now that she isn't the damsel in distress as most people saw her at the beginning
MC/Isa and Isa/Alex relationship will improve in the next update and with that Isa's character will evolve.
