Arrgghhh! I got to the third loop, but kept dying on the spikes. It would be nice if the game restarted from the room where you finished, instead of the begining.
The game looked and sounded ok. The "AH!" when you died was a bit jarring, but not overly annoying.
The controls felt good, and the only thing that annoyed me was that I needed to play the whole thing from the start every time I died.
The use of the theme was on point. This was really interesting take on "one room"- probably my favorite so far.
Keep up the good work!
