That's awesome! Yes I have noticed the problem with the body appearing... I am still trying to figure out why this happens and the sneaking thing is actually a feature that if you sneak a lot it will actually be easier to sneak and harder to walk normally. When you equip the holy water, there is a message on the screen that says "Holy Water (Q)"... but you are not the first person who have missed this so that's fine. The monster does investigate the clock at random and I do not want to make it less random because it's more predictable then and less scary!
Thanks for enjoying the game and being scared!
