Good art and music
I think a "casual mode" would be good, for people who mostly want to explore, as I felt enemies spawned too frequently.
Also the game froze for me on the second room, so I was only able to play the first room.
Yeah I believe something with the spawner is borked, but I've been unable to get a consistent result from it. Sometimes the limited works and others it doesn't. Can you elaborate on what happened when you got stuck? What action did you take or was it just from moving around. I'll look into that tonight though.
