Blue Whale : Game

From being in depression and going to suicide, Alex played a game that actually wants to end his depression by inviting him to play the game for 1 billion dollars without knowing what kind of level he will have to cross... and after crossing level 1 Alex gets kidnapped and brought to the Blue Whale : Game...... Alex has to end this game before it ends him

nor sooner everyone sees Alex's true personality the game made him so worst that no one could kill him or can defeat him the game itself could not kill him despite having the level of life and death

Alex every time manages to come out alive and pass all the level so far.
did the game made him so best at surviving or was he just hiding his true identity?

the question starts to valid as the level goes and where players are dying one by one.
Alex manages to be alive.
