Very decent and quite polished game.
I would argue though that the cursor(heart) is moving very slow. In this type of games (avoid tons of particles) the controlled object's movement is usually immediate and for a good reason: because how much and fast you need to react to the environment. It might be a bit smoothed out. But in your game it follows the mouse too slowly.
Another slightly annoying thing is the intro sequence. In this type of game you restart level dozens of times and watching the same thing over and over again is boring.
