just press the green flag for the (very crappy) animation also sorry for the jittering, I made the art in pixelart.com ,so the transformation from the two websites was pretty rough
I imagine the big haert as the boss fight at the end of a heroes journey. the heroes end goal is to repair the heart, but the heart fights back so he has to defeat it before fixing it. I couldn't think of a character design so thats what the question marks or for. I also like the idea of the character going through multiple waves of enimeis and getting better wepoens along the wave and on wave 20 (probably) the big heart boss (I couldn't think uf a name for the boss either) will apear.
