Can we have a walkthrough?... honestly I tried tree routes and I am able to complete only one. In the beginning of april in Ferdinand route with 4 hearts I cannot do any action, the game give me an error...
This weekend I'll check all the variables around the last week of March: everything works fine for me, but since a few errors keep appearing for some people, I'll make sure they get fixed for everyone.
As for a walkthrough, there's a guide available on the downloads section of this page! ;)
