The controls of this game were very fluid and responsive and felt overall very polished. The use of the theme in the mechanic was very nice and I liked the idea that death was necessary to progress, although I had an issue where once or twice dying would not change the level, which I was unsure whether it was intentional or not. I did feel like each level's two versions were a little disjointed from each other, which is to say I felt like each level was comprised of two separate platforming challenges which you can travel between by dying. I would've liked to see the level design of one room hint at the existence of the other room or something to that effect to make the death mechanic have a more satisfying payoff. Other than that nitpick, however, this was a great, polished game!
