This is a very good choicescript game where you start a team and then race against 8 other teams. The losing team at each stage is booted out.
I really enjoyed this game, though I only got 1 out of 15 accomplishments when I won. It really feels like a gameshow, and it's always nervewracking trying the puzzles, because you know someone's competing against you.
Puzzles include searching for clues, remembering directions, typing in answers to cryptography, etc.
There is a hidden plotline which I didn't find out enough about.
Would play again, and strongly recommend.
