Yay, I lasted 160 seconds!
As for the audio I think it's fine as it is, but I have some suggestions for the gameplay. In the state that it is you can last endlessly by just standing in a point and not moving, like I did... so:
- add a collectible, like coins. Because it will distract players and make them go out of the safe zone and crash into meteors
- add some kind of power up like a 5 seconds invulnerability
- increase difficulty every 60 seconds of survival
- show the player's score in a corner
