Not much to it. Just show this to someone who you want to say happy birthday to. To make the heart stop growing and shrinking, press space. (Press it a bunch of times actually. It usually doesn't work the first time). To make it start flashing again, press g. To reset it press the flag. I'm sorry I can't be more interesting. This is my first one. I'll try harder next time. ❤️
I decided to make this because my mom's birthday way coming up, I was going to do a game, but I decided to start small and just make... whatever you call this.
