I have played this game for about a month or so, here's my take on it:
1. The slow paced and methodical build up of the storyline is sublime at best, so far you've nailed it, I enjoyed the ways the protagonist is corrupted into becoming who she is meant to be, keep up the good work.
2. The questline is in shambles because of the fact that you do follow hints to reach places, but the guidance system is next to non-existent in terms of objectives correlated with the map and quest pointers, so you as a player, are bound to get somewhat lost in the process. In short the pathway is not linear, could be meant to be that way, yes, but do improve it.
Overall, that's my take on the game so far, sure, there are many key points I've yet to mention as I want to do a full review at a later date when the game is more than this.
7.4/10 - a passing grade.
