terminology – How do you call game mode where the time is running out and player can increase time by collecting coins

I am working on an arcade game and I want to make a game mode, where the player has some time to collect coins. When a coin is collected player gets extra time, so the game can continue infinitely. But when the time is run out the game ends.

I don’t know how to name this game mode. Do you have any suggestions? Something like: Time attack?
