I love the aesthetic, It reminds me of "Yume Nikki" and "LISA: The First"
I wish it was a little easier, I felt like I had very little time to try out anything or appreciate the art. It could work much better as an ending to a sort of artsy game where you already know which place leads to where. (like you as the developer do of course. Gotta remember the player doesn't know)
Also sometimes I'm pretty sure I got a bug where I couldn't place a door anywhere. Even in spots I before could.
If it wasn't time based the door mechanic would work better. More similar to "Yume Nikki" / "LISA: The First", which are more of an exploratory "experience" than a game. I think if it's time based there could be some more hints on where doors can be placed.
Music fits the atmosphere and vibe pretty good.
I really enjoyed the game still, the doors actually lead to new differently drawn places. Well done on the "special object" part especially and the awesome art!
