It's an incredibly interesting narrative-centered idea, and I like your interpretation of the theme. Ghosts, and haunted rooms are certainly strange places! I played together with my dyslexic friend, and unfortunately we were not able to reach the end of the game despite trying a few times. I am a little disappointed, because I was certainly curious to find out more of the story and setting. I would have liked to see a lower difficulty setting, or an option to turn off the timer, maybe offering the option to lower the difficulty after dying a few times. Having the player reset back to the start also felt a little bit bad.
I don't think this game needs to be challenging (through the timer) to be fun or interesting or even scary/unsettling. It has a lot going for it in the atmosphere, and narrative!
