Congrats on creating a game! Unfortunately due to some files missing, I wasn't able to progress very far, so my thoughts are based on the first two city screens and some of the sewers.
I liked how each party member had specific abilities that gave them unique roles in combat. I also really appreciated how the confusion and blind status ailments could be useful in fights against large groups. But combat is both too lengthy and too frequent; one or the other can work just fine and help set the tone of the story. But in tandem it just made fighting a chore, and I found escaping to be too unreliable (it's not fun having to wait through five zombies' turns just to get more chances to run away). The fact that zombies with low HP can randomly escape from battle themselves, leaving you unrewarded for your time and resources, is incredibly frustrating.
Though I wasn't able to experience much of the branching paths, I think it's a very neat feature for really any game. In this case, I actually quite like the scarcity of explicit direction; it was like discovering secrets.
