Jumpscare Storey Loop

You, who wielded the legendary sword "Scare Slayer," battle dangerous monsters that threaten all life in the world. Upon entering a building in a monster-infested village, you noticed something strange. No matter how many stairs you climbed, you seemed to return to the same floor. It appeared that the village monsters and the monsters you had previously defeated had been resurrected and had joined forces, attempting to imprison and destroy you with powerful magic. As you paced up and down the stairs, unsure of what to do, you suddenly stumbled upon a frame containing what appeared to be a clue to escaping the building. You had no idea who had placed it there or why, and it could be a trap, but your only option was to follow the instructions on the frame... Find the Jumpscare and escape the creepy looping building. Look carefully to spot the strange happenings, and defeat those attacking you with your katana.
