The music pulled me in deep. I lost myself inside this game. Very silly and VERY fun. The design of the different rooms was delightful and it was enough to get me to brave a room full of baddies just so I could keep exploring.
I found myself getting very disoriented during the scene transitions (such as when you first exit the tutorial room). It was also difficult to tell how close the enemies really were and at what distance they would start to cause me to lose sanity.
Overall, though, this was just a whole lot of fun!
