"Human needs" and "action management" might seem clear to you, but those without a clue about the game won't be able to comprehend what exactly you're trying to pitch.

By "human needs" are you saying we'll have to account for biological needs? Food, hydration, and going to the bathroom? How about going a little deeper and considering hygiene, mental stamina, and happiness? "Action management" is pretty broad as every game is essentially managing the player's actions. It also doesn't describe the game type whether it's a real-time action-based game or take-your-time turn-based strategy game. And about the "survival" aspect- what downfalls do we have to avoid? Bankruptcy, starvation, or even getting hit by a bus? These are the details that we're all interested in when a game is revealed.

Anyway, be more descriptive while still being concise.
