Interesting game with nicely polished artwork.
It was a little difficult to figure out what to do even with the hints because it wasn't always clear what was interactable and what wasn't. I got to the point where I had received the code and wanted to put it in, but couldn't figure out how to get it into the safe.
Wish there was also a way to tell which timeline you were in, something visual besides the one wall and drawer.
Also, some nice atmospheric music could've been nice.
Overall, I see the potential and would love it if the idea was further developed.
