*** NEWS: Screen flashing in Chrome fixed ***

Heart is a zelda-like in which you start with 1 heart instead of 3. This makes the game more challenging, but there's more. To win the game, you need the Heart Blade so that you can fight evil. To wield the Master Sword, you need 3 hearts. The only way to get a heart, is for another player to give you theirs.

To play, you need to log in with your twitter account. The rest of the instructions can be found through playing the game. The game is, sadly, extremely short. I consider you a winner if you: get 3 hearts, wield the Heart Blade, and slay all evil.

There is a leader-board, which will display the players
with the most hearts.

-- CONTROLS --

Arrows to move, space to attack (when you have the sword), x to give someone your heart.

-- KNOWN ISSUES --

The screen transition is buggy: don't hold keys down while the screen is sliding, or the game will probably freeze. Who knew that could be so hard!

Once you get the sword, maybe swinging it too much will freeze the game? I've only seen it once.

-- ATTENTION --
As discovered by @nicolasdet, you need to use the twitter handle, not the user name, of the person1 to whom you give your heart. For example, my handle is @ArrogantGamer, but my name is arrogant.gamer
