Yes! If you get hit by water from the "gun" you are out of the game and lose. You have to be alert and duck and roll and have precision when shooting the water at the other players. You also have to watch out for traps other players set and you can form alliances to help yourself get further in the game than the others. It's a tough game that tests your survival skills! You need to have determination and reflexes to come out as the winner of it. Especially since if you lose, then...
You might have to walk around for a whole day in your underwear.
