Player 1 (Blue) is the denner. Your goal is to freeze everyone by touching them. You have slightly more stamina than other players.
Player 2 (Red) must evade and unfreeze teammates. If you get frozen, you'll take control of an unfrozen teammate.
Tap on your half of the screen to walk to that location. Hold your finger down to use your stamina to sprint to that location. Walking or standing still will replenish stamina.
The game ends when everyone is frozen.
