This is actually so creative, I love it. A short story that's done really well, especially with the different perspectives (the two sides of the priest, and obviously the rat). I also liked the nod to the rat in both paths of initial questioning (the rat tail going by the window for the roommate, and the mention to the experiment from the doctor). The level of detail really made it even cooler to play. Even there being like a mention of spontaneous combustion to the brand of safe that you pass through as a rat.
Also a big fan of the relationship between Roman and Sidney, it's nice to see Roman trusting Sidney no matter what they choose. And I also found it really funny that the people cared more about the rat saying mocha than the fact that the rat was able to say that.
I could also listen to the music on repeat, which I'm doing as I'm writing this review. Good stuff all around, really enjoyed this.
(Just played through the other ending, and there is even that detail in the character icon, the attention to detail on this game is really really cool)
