Hey! Sorry you're having trouble. The idea is to select all the humans. Common mistakes are
1. There's a robot from Star Trek (try googling "Data from Star Trek") that looks like a human.
2. There's a joke that one of the humans (a CEO) is a "sleeper agent." If you select that one, the error message will tell you "fooled by our sleeper agent."
Hope this clears things up! Thanks for taking the time to play the game. :)
