According to this review developers received constant feedback they could have drawn upon to improve their game, iron out bugs ..., based on the handful negative reviews and complaints voiced on Steam forums, it doesn't seem they made good - or even any use of it.

Without communication, something even solo developers manage, without knowing what they are doing right now, this is going to end up as failure. It's never going to be an AAA title, no matter how well polished, the setting is interesting and fresh, but Metroidvania which is what they decided to set themselves up against, have been done to death. Would be sad to see this otherwise interesting game go to waste.

The state it seems to be in right now, it had better not be released here. More for GOG's sake that developer's, because there are already enough abandoned and neglected games to be had here ...
