This is an amazing entry and the art is astonishing for sure. I spent a lot of time playing and enjoying the discovery. I share the main idea of all the comments before, amazing game,
but
// *SPOILER ALERT:* //
I'm not sure about it because I haven't been able to find all finals and I'm not an expert but I think you have mistaken the concept of the mental illness, bipolarity. The bipolar disorder is altering periods of depression (hypomania) and elevated mood (mania). During the mania, the person can be either euphoric or irritable.
Correct me if I'm wrong, but in this game I've understand the illness as something more likely a personality disorder such as schizophrenia (what I don't know about).
If I've understood correctly the girl has this bipolar disorder and that's why she attacked her boyfriend with a knife. And that would be so wrong. I'm telling this because this misinformation could feed the popular idea that bipolarity could be dangerous for social behaviour and this is not true.
Please correct me if i misunderstood the information and I'll erase this comment.
Great game anyways, impressive for a compo! Great job!
