Thanks! Most games can just apply filters or darkness on top of the existing designs. The way I did it here comes just from the limitations of the Bitsy Engine. You can find some similar things in other games, yet, right now, I can't name you any of them.
I had the inspiration for the ending days ago, but I started making the game way too late so I had to reduce the scale. I was gonna make a couple more enclosures but couldn't programm them on time.
If I had time I would try to find other way, but what the game is doing is using invisible objects for the dialog that happens inside the room like "What a weird dream [...]" so the bed is in fact surrounded by the same object that says that exact sentence so you don't miss it, same with the enclosure exit and all the room-changing tiles it has around.
