What is the combat like? Turn based? Quick time events?
Combat is basically you "Clicking at the right time".
This slider moves around the screen and you can shoot freely as fast as you can (As long as you have bullets in your gun)
However, the shots will only hit the bandit if they are within the "green area", the others will be wasted bullets and you will just lose ammunition.
The bandit's counterattack is already turn-based, you receive them whenever the slider reaches the left and right corners.
The damage you deal is random, with parameters defined according to the gun you are using (better guns, higher random values), and the damage you receive is also randomized according to the difficulty level of the bandit you are hunting.
