Hi, great little puzzle game! It was relaxing and I think I'd play more with a bit more content. The premise is good, I like the nature of the puzzle elements and it did make me think a bit.
A couple of small things: One of the levels felt a bit long, I think it was level 3, where there is a lot of walking to gather hearts. I feel like it would have suited the second level better with slightly shorter run distances.
I also noticed a bug in the tiling of the health gauge:
Great job!
