Developer Notes
 
 
Hello guys! In this update, I took the time to do some critical under-the-hood maintenance and keep all ready for the v0.6 release. I also investigated and resolved another issue where X_17 could sometimes lose his dynamic horror behaviors (stalking, vanishing, and rage transitions).
 
I still know that many of you wish music/mob to be configured, but my research is still failing about that and I'm still working hard on that, so I'm really sorry for that expect it very soon, the process to make that happen is still very complex to me, but slowly becoming studied.
 
 
Note: this mod is still WIP, and much content and changes will be done with feedback and my vision of this project. Please be free to give any suggestion or comment about anything you may wish. Thanks!
