Interesting take on the theme. The pixel art is nice and reads well. It was a really cool feeling when I understood the mechanic of dragging your own hearts down to use as platforms and such.
Also, just a note for future reference. When the submission form asks "How does your game fit the theme?", it is asking for an explanation of the ways your game was inspired by or fits the theme of the game jam. "Yes" is not a good answer to that question. It doesn't lead to an understanding of your inspirations or why you believe the game is a good fit for the jam. That is a judging criteria, and I did mark you down for a poor response.
