Thank you so much, Cicada! I read throughout the google doc before replying here and I'm back to work to fix those bugs!
Your feedback is incredibly valuable to me, it's exactly what I wanted  ;w;
Those things slipped through the testing and I'm quite embarassed but also (after reading your doc) motivated to fix them!

The door picture is fine! I agree with you, it will work a lot better like that :) also other things will be a quick fix I think...
As for the portraits\sprites, they were made by a talented artist names Ghoulless (I did the animations and the CGs though, like the red eyes), I'm glad you like them! 

PS: meanwhile I fix those, as for the piano room I think I got what triggered the instakill: you said you exited the room during the timer, so once is set to zero and you get back to the room it activates the instakill (I definetly have to fix this) @w@ to stop it you have to check the left bookshelf in that room during the countdown
