Use the up and down arrows to control the pulse speed, the left and right arrows to change the backdrop color, and the spacebar to toggle two different heart shapes/styles. Sorry, I don't know why the thumbnail is messed up... :/
IDK why I decided to make this random being heart animation, I guess you could say it has something to do with Mother's Day? :P Feel free to leave a love just to be ironic! xD Heart sound effect credit to soundjay.com
