Falling in love... Nice. Poignant.
All these people below me suggesting what to add to make this a fun game just don't get it.
Yeah restart button, fine.
There's a message here.
You collect a heart but if you miss any after than you fall and die. But if you don't collect any hearts the game continues on and you're forever unharmed.
He/she is saying you fall in love you set yourself up to be hurt. You don't fall in love, you don't get hurt.
I like this. It's got poignance to it. It's like a poem in the form of a game. I'd like to see more stuff like this. Except something with a more wholesome ending. Then again it's good that you're not blatantly spelling out the message for people.
