Hello, thanks for playing my game.
For the horror part, yes you are right that it's not that horror-y because the original plan was to draw horror assets for the game jam but I found that it was hard for me and I need to learn pixel art and Aseprite first, that's why I added that there was only ONE horror element, particularly the scream.
Now let me explain the scream: After you insert a token on a corrupted cabinet, a hand grabs you from inside the machine and sends you inside the machine, which the player then screams then gets corrupted (hence the breaking voice of the scream). I found I needed to learn how to draw and animate that first, because I barely have experience with art, so I apologize.
And for the end card telling you what you missed, I think that's a bad idea as this: reduces replayability, streamability, puzzle solving feeling, and the psychological horror element of the fear of the unknown. These were the assumed reasons why Exit 8 and That's Not My Neighbor don't show you what you missed in the end as well.
Thanks for the feedback!
