Such a nice warming story for the theme interpretation!
I liked playing the game until wave9 and than I lost. Maybe I was too reckless (or didn't like that the hearts spawned away, when they are in a bunch of enemies).
I liked all the enemies and the elites where very good programmed with unique attack patterns. Maybe the game was a bit hard (could be skill issues). I also didn't see much good with the ghost fish cause it never hit anything it was always on a place where no enemies where when I flipped.
I loved the art and all the sounds and music really charming and cute.
