You're a ball of goo jumping, swinging and sliming your way through space. What a coincidence, that's exactly like the main character in puzzle platformer Grapple!
Crafted by a five-person team from the University of Texas at Dallas, Grapple doesn't need a reason for a ball of goo to be travelling through space sticking to purple things. It's all about the challenge, and there's no time to worry about whether or not the blob you just made fall off a platform had a family.
Here's the official description from Grapple's Steam page.
Grapple is a 3D puzzle platformer. You can fling, swing and climb across everything in Grapple. Different surfaces react uniquely to your gooball. Grapple is as fast paced as you want to play it. With multiple checkpoints and unlimited lives your skill is the only thing slowing you down.
It probably did have a family though. I am a monster.
