What do you mean with "opening window"? Do you mean a literal window/screen at the beginning or overall the first 5-10 minutes? :)
Yeah I see. I have to make the dialog either skippable or maybe even just a one time thing. The automatic can be turned on with "A", but I forget to put a label or something for the player to know. In general I have to make something like a controlsheet or tutorial for the player to look at. Yes the combat throws off a lot of people, so I definetly have to work on that. For the possession not beeing felt during gameplay/battle... maybe it would help to animate the demon acutally visually coming out of her and covering her eyes? Or have another indicator for the inner demon disrupting the player. So people don't get confused whether it is the inner demon from the dialog or the enemy walking around, who is interrupting them.
Thank you for your detailed feedback! :D
