I did not plan to use this parameter in prohibitive numerical values. I planned + - 20-50. Cheating fans will find a way to cheat the game without this option. And if you use it within reasonable limits, then I don’t see any imbalance.
As for shooting at neighboring cells, burst shots through walls look no better. "Forced shot" too. In addition, it is not always possible to hit the enemy with a splash or hit by shooting at neighboring cells, especially if the target is flying.
In general - such an opportunity to make the player tense up a little and learn how to use the keys.
