I'm not sure where to write this, but when I tried running the game, whenever I entered a room with more than 1 enemy, the game slowed to a crawl. One example is my C:/users/<username> folder where I have 38 folders and 13 files.
My computer is Windows 10 (latest) with 8 GB of ram, and a 1.80 GHz Intel i5 processor.
It might run better one of my more powerful machines which I was about to go try.
