Hey, thanks for trying the demo, glad to hear the lighting works out well.
There probably won't be any real jump scares or the like in the final game, well I guess it depends on what someone defines as a "jump scare" but yeah.
As for reading about the creatures, story and such:
I'm pretty much only focusing on trying to do some "environmental story telling" so there probably won't be too much reading in the game. (apart from item popups and a few exceptions)
