Yo! This game is awesome! :D It such a small and contained room but with a lot going on under the hood! :D The room evolving overtime kept that space alive and made every object a possibility to find something new! One of my favorite moments was when you used that shader to show 2 different versions of the same room! I have been trying to do that and it just never really fit narratively in my games. I think that if you were to expand on this project, it would awesome to have that lens being used a little more :)
I did have trouble with placing objects where they needed to be and felt that it distracted me when the candle I was holding would be flying all over the place (although at times it added to the demon stuff :P)
I hope that you do plan to expand on this and if you do, I would love to give it another go!
