I'm sorry you feel that way. Unlike a few other visual novels out there, I make Demons Within all by myself as one person and it's a lot to coordinate and get done for each update. Because of its descriptive, book-like style, Demons Within also takes a lot more writing than something more dialog-based.
Regardless, I strive to keep a somewhat consistent update schedule as best as I can even when life gets in the way or motivation wanes. The last update had a significant delay because I overshot on the art department and how much of it I could realistically get done in time. I apologize for that and will try not to make that mistake again.
I'll do my best to keep the schedule and keep making the game better and better as I work on updates. I work on Demons Within full time every single day and while I can't promise things to be even faster, I'll work hard to do what I can to improve!
