Stonetooth Dentist

You're a dentist for the mountain trolls. Since they eat rocks you need to use actual guns to remove the debris stuck between their teeth. Now now, we know that guns are not supposed to do that but what can we do? Using them for healing instead of violence makes total sense in this case. They won't make it easy though - they are very impatient and their massive size means you'll be operating under conditions similar to an earthquake.

Aim with mouse, left click to shoot. Your gun fires a burst of 3 shots. Remove as much debris as possible with your limited ammo to achieve a high score.

PS : Bolded parts are the themes I went with for this submission to BYOG 2022.
