it wasn't happening for me for some reason. i tried it twice, refreshed my browser, cleared cache – nada.
Sorry for the late reply ;') Strangely, I've heard of this bug before, but I can't really say why this happened, since I never encountered it myself...
I'd reccomend using another browser or downloading the game(if possible?)
I'm curious, did you get the dream sequences? (They trigger after you get a certain amount of dead ends)
Same for me, got 6 endings, I think i got all the dreams and the last one was repeating itself on each restart, but no trigger. I know what happens after because I saw a walkthrough but wanted to experience the game myself. I'm using firefox, there is a 5 in the bedroom too.
It's a nice and cute game, I enjoyed watching and playing it and a perfect match for the theme in all aspect, good job! :p
