It's a cool little game and while it fits the theme, I would have liked to see some choice in the matter. As it is, you have to lose lives to progress, or at least it felt like it. Maybe you could choose an easier path that you had to die once to be able to get through, or a very difficult one that you can reach at full lives? If you added a checkpoint just before such a sequence, I think it would give the player a choice on how to proceed.
I liked that you included music at all, considering it's a jam game, but it's very loud and repetitive. I feel a longer track would have improved the experience significantly.
