Thanks! It lacks polishing, indeed. Regarding turret building: if you don't match them, they will fire really rarely. So quality of the match affects rate of fire. A good example is the one turret, with which you only need to set a big red canister: when it on place the turret works like a machine gun (a lot of damage, but runs out of bullets fast), but the canister is up, it will fire like a standard tower (or slower).
