Amazing! Very fun indeed, great attention to narrative, with a personal touch and subtext. I agree with the other comment: the death animation is really good! Way to go! I think that after the death, you could replace "You lost" (in the narrative text) with "You blew it!".
That's more of a "relationship word", and also a pun. I'm a casual gamer, so I couldn't get past the 2nd level, so the story didn't develop fast enough for me. I expect there's the possibility of reinflating, eventually?
I loved the bold choice of metaphorical images to compose the narrative. I imagine the thought process was something like: take a deep breath -> we are like balloons in love -> we feel inflated or deflated by some romantic happening. Love requires energy, another word for energy could be gas, and so on.
