You have 20 seconds to prove you're not human.

A minimalist cyberpunk comedy.

AI has taken over. Xeno run rampant. Earth is at peace. Humans are thought to be extinct. But they are not all gone, no. You are one of the last humans that remain, aren't you? You stay undercover the best you can, but you get caught unawares...

Over a dozen questions to test whether or not you're human. Replay it to answer all of the questions. Questions and answer orders are random.

Strange, I’m not sure what’s wrong. Could you try another browser or maybe temporarily disabling some extensions?

I downloaded the game myself, and it worked fine here.


Awesome, glad to hear it!
