I really like the music in this game, it definitely helps creating a creepy atmosphere. I also really like the unsettling interactions between the characters. And big respect for adding voice acting! One can really feel the effort that went into this game and it all works well together. I really enjoyed the game, also because I am a fan of the theme. I ran across a few oddities that I could report and I did have trouble with catching one hint, but otherwise everything was clear enough.
A very nice game overall, considering the short timeframe. And yes, Rat is definitely the MVP. A brave and adorable rodent :)
