Nice idea, battle room to room, good choice of assets. I liked it. Not sure if it was just me, though, but I had a few playability issues. The camera sometimes would zoom way in making it hard to see. Sometimes I could move normal speed, sometimes fast (which seemed to be a power up) but then sometimes I'd also move at maybe 1/4 speed... very tedious getting from room to room. Finally I ran into a room where no matter what direction I faced all attacks only happened to the right side of the screen. If you can resolve these glitches I think this could be a really fun game especially with your procedural generation making in unique and fresh every time
