Well that was creepy, I liked the story. Pretty well written despite a few minor typos.
I'm not sure how I feel about the timed events. They are both centered around memorizing a page with a bunch of instructions, which isn't that interesting. The first one I didn't expect it at all and was basically guessing. The second one somehow I also didn't see it coming but then it didn't really matter since I could retry after every fail (which I preferred because it would be horrible trying to memorize).
Then there's the caution point system. It's a system that does not feel impactful since I as the player don't know how many points I have or need for specific choices in the game. If I had too little caution points would I not have been able to get the good ending? Maybe if some choices displayed "8/5 caution points required" or something then it would be clearer.
Overall a pretty solid visual novel with an original story and nice art! I got ending 2. Keep it up!
