So I got some suggestions.
You could add an option for ironsights instead of a advanced crosshair.
Also an option to carry multiples of these weapons at once. It was common practice to carry about 3-5 loaded flintlock pistols on your person.
And then I guess the next step is to include like an ammo system.
Other than that if you plan on making more I did like some of the crazier weapons from gravity cat. I just wish his weapons had cool reload animations and otherstuff like yours.
Like the fire musket, rocket launcher, etc
