Hi Jimmylex!
Aw, I'm so excited that you're as excited as I am to release LYTP tomorrow.
So, I don't want to spoil too much this early on. All I'll say for now, is that members of the cast can be saved, which will lead to multiple outcomes at the end. Your choices will definitely impact the plot, however I'd also add that not all choices make big waves. Some simply open up new insight into a character's thoughts or personality etc.
I've been told by our playtesters / QA initiative that the game is indeed VERY gory...but that's why it was so very impactful and unexpected considering how polished the art style is (their words, not mine).
