So I found every item but never found the use for the notes or umbrella.
I'm pretty sure the umbrella lets you go outside however when I did and used the tombstone key I just died so not sure. I tried about 5 times and no difference so no idea.
The game was fun but the jumpscares were scary but annoying (also very loud). I was confused as to why you could click somewhere and just teleport there as you can skip every window by doing that.
Great first game jam. Keep it up. (Also couldn't go back to the menu so had to reset)
