Do you have free will? You decide the answer is 'yes.' But it's a question that Sentient posits as it traps you inside a tiny room.

It's you and a voice on a speaker system, which tells you to do things, baffling things, inside your miserable little cell. Turn around a number of times. Face that wall, that sort of thing. And, to respond to binary yes/no questions, you fling a tennis ball to the left or right of the room.
It doesn't really go anywhere, this 'playable teaser' for the bigger Forma project. But it does offer a glimpse of a world, an unsettling and creepy one at that. I'm intrigued to see what Forma will offer next.
