After a few rooms I got to a black screen. Idk if that was just the end of the game. I also didn't understand what the 4 squares on some of the doors was.
I really liked the weapon. I was a really unique idea. It felt good to use too.
If this was more completed I'm sure it would have been great.
(PS I liked how the .exe was called r-ng-ougelike. I chuckled when I saw that)
