Great platforming and level design. The music, bits of singing, and occasional exposition its really do wonders to contribute to the spooky atmosphere. I loved the flower mechanics to life, you could go out of your way to get them to see mor eand more color come back to the character, but if you did then you typically had to go back over dangerous areas, wher eyou might lose the life you got. It was clever.
I liked the two endings as well, it took me several tries to get the second, which made it satisfying when I finally did.
If I had to nitpick anything, it'd be the background and designs on the block. Once you get to the end, it really just doesn't look like they fit. Also, I would have liked to see more of the narrative to describe how the girl got to where she was. BUt these are just minor points, it's a really fun game overall.
