You did very well on the art and audio! Those two fit the theme very well. Personally, I felt a bit trapped and incapable of escaping, due to the fact that the player moves slower than the monsters. Every time a chaser came after me, even when I tried to run, it got me. That's not really fair in my books. Maybe we finish 99% of the game, and before reaching the last piece of broken heart, a monster starts chasing us and inevitably catches us. Game over... Start again? I dunno...
Please be careful of making your games fairly winnable, not just winnable by the blind luck of never encountering a game-ender.
