There are no instructions, but users can send this character into the black hole to see what happens. I have no idea how to describe "Bla Bla" other than it's a fun, interactive web film in which you control the characters.
What's fun is there's minimal instruction, so it's up to you to figure out what to do. Sounds annoying, but it's not.
"Bla Bla" is six chapters long, but they go by quick. At the start of each chapter, you'll find yourself pondering what you see before diving in, then adjusting your movements as challenges arrive.
I couldn't tell you what the overall theme is, was or might be, but it doesn't matter.
Just give it a spin for fun.
